[AFMUG] Sitemonitor question

[Craig Baird]

Anyone know how long the cable can be between a Sitemonitor base unit  
and an expansion module?

[AFMUG] SiteMonitor Question

[Plexicomm Admin via Af]

So I have two SyncInjectors connected to this SiteMonitor. The second one will 
not communicate properly (see screen shot below). I tried rebooting the base, 
different jumpers, defaulting, no luck. All three items are brand new.

It depends.   It really was designed for inside an enclosure or small
building.   I was going to spend some time characterizing this distance
today,  but ran out of time.

I'm guessing you'd be ok in a low power rf environment for dozens of feet.

Just had this his happen with one of mine out of the box.  One port 
would not provide POE either,  Packetflux RMA'd the unit.

Re: [AFMUG] SiteMonitor Question

Looks like something goofy with the second sync injector.  Data on index 
2 looks sort of like the data a sync injector normally shows on the 
String I/O tab (like below).  Try unplugging the second one, and see if 
it feels better.


If it does, you can try setting the serial # to zero then rescan to see 
if it will pick it up.

Re: [AFMUG] SiteMonitor Question

[George Skorup (Cyber Broadcasting) via Af]

I have a SyncInjector H1 on an old Base-1 and I get the same thing for 
the exp. description. It happened when I renamed some of the 
SyncInjector related binary or analog items. It works, so I just left it 
alone.


Mine is running 24-Apr-14. That's a firmware load Forrest sent me to 
debug some detection issues.


Also, when I refresh the String I/O, the base unit crashes and the HW 
watchdog recovers it. I haven't had any time to mess with it or email 
Forrest about it.

Actually now I look more closely at the screenshots, this might not be the
issue the firmware fixes, but let's start there since that fix may also fix
this.

[AFMUG] Sitemonitor question - different voltages

[Paul McCall]

Can the sitemonitor have two different voltages on the 2 inputs that it 
monitors / powers from?

We have a lot of them setup in the field with a 110vac – 24v wall wart to 
monitor commercial power.  And, the 2nd input is off the 24v battery array. 
Batteries are all 48v now, so wondering if I need to buy a bunch of similar 48v 
wall warts or whether the SiteMonitor can deal with the 2 different voltages 
and I don’t need to buy anything 😊

[AFMUG] Sitemonitor Question with Relay

[Paul McCall]

My service manager seems to be struggling with using the Sitemonitor Relay 
contact to trigger a 48 Relay that we want to use to power cycle the whole 
tower if necessary.  So, Packetflux states that the Relay control is maximum. 
30v 1amp.  So a little more than half the amps at 48v.

So, in the past (lighter loads on towers) we used this to trigger an external 
relay and "open" the ground to the main power feed going up the tower.  At 48v, 
we sometimes are around 2amp on the bigger towers, some perhaps a bit higher 
still.  (with a 48v relay).

We should be able to use the Sitemonitor to somehow accomplish it.

Can anybody comment on this?

Thanks!

Yes - it can accept multiple voltages on PWR1 and PWR2.

Re: [AFMUG] Sitemonitor question - different voltages

[Josh Luthman]

That's exactly what we use it for.  Volts1 is utility (we use some random
wall wart) and volts2 is the battery.

Re: [AFMUG] Sitemonitor question - different voltages

[Bill Prince]

We use inputs from 12V to 56V as long as it's a Base II; mix and match. 
They all have to be negative ground too.

Re: [AFMUG] Sitemonitor question - different voltages

[George Skorup]

Be careful connecting +48VDC to a SiteMonitor. Verify it's a Base-II 
first. The old Base-I's are limited to 30 or 32VDC on both inputs.


I typically connect the pwr1 input to my main rail, usually 24-28VDC so 
it's safe for Base-I's or Base-II's. I've been recycling a lot of old 
Base-I's from site rebuilds the last year or so. Pwr2 gets the wall 
brick for utility monitoring. I try to dig out old SyncPipe power 
supplies if I can find them because they're linear. We're at many towers 
with crappy power, or those 3-phase sites that lose a phase and we end 
up with <100VAC and our UPS transfers to battery. Most switching bricks 
will operate down to 80-85VAC. Has happened more times that I can 
remember. Site goes down because the batteries ran down, yet we never 
got a utility power alarm. The linear brick lets you see the voltage 
situation. Problem is, they're getting pretty hard to find now.

Re: [AFMUG] Sitemonitor question - different voltages

[Adam Moffett]

I think it draws current from whichever port has the higher voltage.
If you did +24 and -48 I bet that would be bad.

Of course.  You'll also be able to monitor both at the same time.

Conversely an RB750 will only report the highest of the two voltages.

Yup, it works fine to mix... pwr1 and pwr2 definitely don't both have to be
the same. We typically have 24v on one and 48v on the other, on sites where
we're using both.

Re: [AFMUG] Sitemonitor question - different voltages

[D. Ryan Spott]

I have 2 differ t voltages on mine. 

On a 24VDC site I have Up to 31VDC on one input. It powers the unit and I 
monitor the sites status with it. 

Power supply 2 is a wall watt plugged into my remote genset. When the genset 
comes on I get 24.3VDC on that power input. This tells me the genset is 
running.

Yes, there is a relay output on the siteMonitor II that you can trigger via 
SNMP or web interface.

Subject: [AFMUG] Sitemonitor Question with Relay

My service manager seems to be struggling with using the Sitemonitor Relay 
contact to trigger a 48 Relay that we want to use to power cycle the whole 
tower if necessary.  So, Packetflux states that the Relay control is maximum. 
30v 1amp.  So a little more than half the amps at 48v.

So, in the past (lighter loads on towers) we used this to trigger an external 
relay and "open" the ground to the main power feed going up the tower.  At 48v, 
we sometimes are around 2amp on the bigger towers, some perhaps a bit higher 
still.  (with a 48v relay).

We should be able to use the Sitemonitor to somehow accomplish it.

Can anybody comment on this?

The typical solution with a light-duty relay is to use it to control a

Re: [AFMUG] Sitemonitor Question with Relay

[George Skorup]

I use the temp control module for heaters and fans. Same concept. The 
external relays are 24VDC coil. Contacts rated for 125VAC/10A. The load 
is on the normally-open side. The temp module calls for heating or 
cooling and triggers the correct device. e.g. turn on the fan if TempA>30C.


You're just using the contacts on one smaller relay to control the coil 
on another larger relay. Pretty simple.

[Adam Moffett]

Get a DIN mount DPDT, wire it so your load is on the normally closed 
contacts.  Run the control circuit on the DPDT through the normally open 
contact on the Site Monitor.


I'd bet a Google search can give you diagrams.

Re: [AFMUG] Sitemonitor Question with Relay

[Christopher Tyler]

If you are using an external relay the load shouldn't matter to the SiteMonitor 
at all. The load would only matter for the extrenal relay itself. The 
SiteMonitor doesn't supply power accross the relay output so you would have to 
supply the external relays coil voltage across the site monitor contacts. You 
would only have to ensure that your coil volts and amps don't exceed the Site 
Monitor rating. And that should work just fine.

30v 1amp.  So a little more than half the amps at 48v.

Re: [AFMUG] Sitemonitor Question with Relay

[Forrest Christian (List Account)]

The relay is rated for 2A@30V, and 60W above that.

See https://www.mouser.com/datasheet/2/315/mech_eng_tx-1075670.pdf figure 1
on page 3 for a visual of this.

I'd recommend that you test the relay operation with an ohm meter before
trying a circuit.  There should be conductivity between C and NC and none
between C and NO when the value is set to zero, and opposite  that when
it's set to a one.

If it doesn't work,  upgrade the firmware to the latest and try again.
There have been a couple of relay bugs fixed in recent memory.   Also make
sure that the relay on above and below rows  are set to a very high and low
number since if that is enabled it will override the relay.

Re: [AFMUG] Sitemonitor Question with Relay

But, is the relay switching in the Packetflux bearing any of the load at any 
point?   I would think not, but the answers are a bit confusing, as though it 
is.

I would think most basic relays could be triggered successfully with much less 
than 2A

Re: [AFMUG] Sitemonitor Question with Relay

[Christopher Tyler]

Generally the tirgger is measured in milliamps. Your load shouldn't be running 
through it. But rather through the remote relay.
See the attached image for a quick wiring diagram. I think I drew the diode 
backwards, I was in a hurry.

Re: [AFMUG] Sitemonitor Question with Relay

[Forrest Christian (List Account)]

Depends on the load and how you wire it.

For smaller sites I've been known to use a small 24VDC fan for ventilation
which consumes less than 1A, so I switch it directly with the relay.

If you get closer to the relay rating you should use an off board relay,
 and then you use the on board relay to control the power for the coil of
the off board relay.   The on board relay just carries enough current to
power the coil which isn't that much except for very large relays.

Give me a few minutes and I'll send a drawing which might help even more.

OK, that makes sense Forrest.  That demystifies things a bit

Depends on the load and how you wire it.

For smaller sites I've been known to use a small 24VDC fan for ventilation 
which consumes less than 1A, so I switch it directly with the relay.

If you get closer to the relay rating you should use an off board relay,  and 
then you use the on board relay to control the power for the coil of the off 
board relay.   The on board relay just carries enough current to power the coil 
which isn't that much except for very large relays.

than 2A

The relay is rated for 2A@30V, and 60W above that.

See https://www.mouser.com/datasheet/2/315/mech_eng_tx-1075670.pdf figure 1 on 
page 3 for a visual of this.

I'd recommend that you test the relay operation with an ohm meter before trying 
a circuit.  There should be conductivity between C and NC and none between C 
and NO when the value is set to zero, and opposite  that when it's set to a one.

If it doesn't work,  upgrade the firmware to the latest and try again. There 
have been a couple of relay bugs fixed in recent memory.   Also make sure that 
the relay on above and below rows  are set to a very high and low number since 
if that is enabled it will override the relay.

The typical solution with a light-duty relay is to use it to control a heavier 
relay that carries the actual load.

Yes, there is a relay output on the siteMonitor II that you can trigger via 
SNMP or web interface.

Subject: [AFMUG] Sitemonitor Question with Relay

My service manager seems to be struggling with using the Sitemonitor Relay 
contact to trigger a 48 Relay that we want to use to power cycle the whole 
tower if necessary.  So, Packetflux states that the Relay control is maximum. 
30v 1amp.  So a little more than half the amps at 48v.

So, in the past (lighter loads on towers) we used this to trigger an external 
relay and "open" the ground to the main power feed going up the tower.  At 48v, 
we sometimes are around 2amp on the bigger towers, some perhaps a bit higher 
still.  (with a 48v relay).

We should be able to use the Sitemonitor to somehow accomplish it.

Can anybody comment on this?

Thanks!
