If you turn on your Omniguard II and the
only thing that appears on the screen is "Omniguard II" or "Initializing..."
there is probably a "paper jam". The Omniguard
II does not have the ability to detect if the printer is
unable to move so it freezes on the introduction screen. Unplug the unit and check the printer for
an obstruction. Once the obstruction has been removed your Omniguard
should get beyond the starting message and function normally.
Omniguard IIa, III, IIIa, 4
These versions of Omniguard
display a "Paper Jam" message when the printer is unable to move.
Once any obstruction has been removed, you will need to turn the printer
back on by pressing the "PRINTER ON/OFF" button to reset the paper jam.
If you are unable to remove the obstruction through the
paper outlet slot or the printer is really dirty then you will need to
either dismantle the Omniguard to get to the obstruction, clean the printer,
or send the unit in to ESi for repair. If the Omniguard is
under warranty, dismantling it will void the warranty.
All Omniguard printers use thermal paper. If the printer moves but doesn't print after
changing the roll, the paper may not be thermal paper or the roll may not be installed
correctly. Verify that the paper is feeding from the bottom of the roll and printing on the
shiny side. If neither side is shiny, it's not thermal paper. Contact your Omniguard dealer
or call Engineering Solutions at 206-241-9395 to order the correct paper.
There are a number of possible reasons the Omniguard is unable to properly read
the amount of vacuum in your containment:
If you have a larger size hose than the pressure inlet nozzle,
then you could have a leak causing erroneous pressure readings. Use
a hose with the proper inside diameter which you can purchase from us or
we can give you the diameter so that you can find the right hose.
If you have wrapped tape around the nozzle to compensate for
the larger hose and then cut the tape off you might have gouged the nozzle
causing a leak. You will need to send the unit in to us so that we
can replace the nozzle for you.
If you have tried to unscrew the nozzle, then the internal
hose may have become disconnected. You will need to send the unit
in to us or you can dismantle the Omniguard to reconnect the hose.
If the Omniguard is under warranty dismantling it will void the warranty.
Make sure that when you put the hose through a cut slot into
the Containment Area that the slot is sealed against the hose.
If the reading is at full scale and will not respond to pressure
changes, go through these steps:
Disconnect your hose(s) and see if the reading changes.
If it does, then you have an obstruction in your hose. Try a different
hose.
If the reading doesn't change: For the Omniguard II the unit
will need to be sent in for repair, for the Omniguard IIa, III, IIIa, 4,
try pressing lightly on the nozzle(s). If the pressure changes then you
will need to Zero Calibrate the Omniguard.
If the reading doesn't change, check to see if there is an obstruction
in the nozzle. If there isn't then the sensor is probably damaged and
the Omniguard will need to be sent in for repair.
If the reading is not what you think it should be, remove the hose(s)
and check to make sure the reading returns to zero. If it doesn't,
then for the Omniguard II send it in for repair, for the Omniguard
IIa, III, IIIa and 4, Zero Calibrate the unit. If it does return to
zero and you still think the reading is not what it should be send the
Omniguard to us and we will check the calibration.
If an Omniguard II displays this message when turned on, the internal
battery has probably failed. You can send the unit in for repair or replace
the battery yourself.
To replace the battery, remove the four button screws on the bottom of the case
and pull out the front panel which has the ciruit board attached. Remove the
battery and take it to Radio Shack. They will be able to provide a suitable
replacement. Install the new battery, replace the battery cover and re-install
the front panel in the case using the four screws.
If the unit is an Omniguard II see the section for Paper
Jam. If it is an Omniguard IIa, III, IIIa, 4 then the unit
will need to be sent in for repair.
Check to make sure you are using the
correct power adapter. The adapters output should be 6VDC at 1.2A
with the outer shell positive and the inner negative. If it isn't,
you can purchase the correct one from us. If it is, try another
adapter and see if this fixes the problem.
Omniguard II
If trying a different adapter doesn't fix
the problem, the internal battery is probably dead and will need
to be replaced.
Omniguard IIa
If trying a different adapter doesn't fix
the problem, the unit will need to be sent in for repair.
Omniguard III, IIIa
Check to see if the power cord has
been closed in the case lid. If it has, send the Omniguard in for
repair. If it hasn't, you will still need to send the Omniguard in
for repair.
Omniguard 4
When the Omniguard 4 is first plugged in the
LED on the front panel should flash green. If it does not, make sure the
outlet you are connecting to has power. If there is still a problem let the
Omniguard sit unplugged for at least 10 minutes (or overnight if you have
a chance) and then try again. If the unit still does not work you will
need to send it in for repair.
The Omniguard 4 can be monitored remotely by connecting an external modem to the serial port on the front panel.
Almost any serial modem should work with the Omniguard 4 (a USB modem will not work). Modems with a speed of 14.4kbps or faster are recommended. We have had problems
with the Motorola modems and can not recommend them for this application. The Practical Peripherals modems seem to work quite well and can
be had for as little as $2 on eBay.
The Omniguard 4 can be monitored remotely by connecting an external modem to
the serial port on the front panel (a USB modem will not work). You should test
the modem while you are at the job site.
Omniguard 4 with two USB ports
Connect the modem to the Omniguard
using the Omniguard USB Port Adapter and the serial cable provided with the modem. Then connect the modem to a
phone jack and hook up the modem's power supply. Turn the modem on. Go to the
Telephone Modem window on the Omniguard. Select "Test" from
the Modem Setup window. The Omniguard will test the Init String and let you know if
it worked ok.
Omniguard 4 with serial port
Connect the modem to the Omniguard
using the serial cable provided with the modem. Then connect the modem to a
phone jack and hook up the modem's power supply. Turn the modem on. Go to the
Modem Setup window on the Omngiguard. Make sure the "Dailing Prefix" is set
correctly so the Omniguard can connect to an outside line. Select "Test" from
the Modem Setup window. The Omniguard will attempt to call a computer at
Engineering Solutions. We no longer maintain
a computer to reply to this test but watch the Omniguard screen to be sure
the Init String works.
If the modem test is successful but you are unable to connect when you use
the Omniguard Communication software to call the Omniguard from your computer,
there may be a problem with the computer's modem setup. First, make sure you've
selected the correct COM port for the modem. Also make sure the phone number
entered is correct. If these are correct, you may need to enter a new Modem
Init String. Enter each of the strings below into the Modem Init
String field in the Connect window and then press Ok to try it
out.
If part or all of the Omniguard 4 display goes blank or the display becomes garbled, turning the unit off and then on again may temporarily
fix the problem. Note that while the display may not look right, the unit is still monitoring and logging pressure correctly.
To prevent this problem, download and install the latest version of firmware
from the Omniguard Software Downloads page.
For all other versions of Omniguard, the unit will need to be sent in to repair any display problems.
Clearing Job Logs Or Returning Unit To Factory Default
To erase all the Job Logs in an Omniguard 4, press the Start Job and Exit keys at the same time while the
unit is turned on and showing pressure. You will be prompted to confirm that you want to erase the log. To confirm, again
press the Start Job and Exit keys at the same time.
A key combination can also be used to erase all the Job Logs as well as return all settings (Alarm Setpoints, Log Rates, etc.)
to factory default. With the unit turned off press the Start Job, Exit and down arrow keys at the same time. The unit will
turn on and show "Factory Default" on the startup screen.
Setting up a containment site can be a complex process and our support staff can not provide detailed design assistance.
