Paper Jam

Omniguard II
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.

Printer Moves But Doesn't Print

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.

Incorrect Pressure Reading

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:
    1. 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.
    2. 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.
    3. 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.

"RTC Failure"

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.

Lock Up

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.

No Power

Omniguard II, IIa
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.

Keypad

For all Omniguards, if any of the keys are unresponsive, the unit will need to be sent in for repair.

Choosing An External Modem

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.

Can't Connect To Omniguard 4 Via Modem

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.

Display Went Blank Or Became Garbled

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.

Omniguard WiFi Adapter Will Not Send Emails

Early in 2014 we changed our hosting provider. This resulted in a change to our mail server settings. If you are using the "Test" email settings for your Omnigaurd WiFi Adapters (which use our mail servers), your adapters may connect to your WiFi network but can not send emails (WiFi LED will be orange).

To fix this problem you will need to reprogram your WiFi adapters. Until an update to Omniguard Communications is available, you will need to manually change the "Outgoing Mail Server (SMTP)" from "smtp.engsolinc.com" to "mail.engsolinc.com" in your WiFi setup and then reprogram your WiFi adapters. When Omniguard Communications is updated, the "Outgoing Mail Server (SMTP)" will be set to the correct value automatically but you will still need to reprogram any WiFi adapters that were programmed using the old setting.

Internal Cell Modem Not Working

Omniguard Cellular units (distinguished by "OMNIGUARD CELLULAR" on the outside of the case and serial numbers beginning with "C50") have a built in cell modem that can be used to email notifications and daily logs. This feature is free for the first two years but you must register to activate it.

You also must have V9.2b2 or later firmware. Firmware can be updated by downloading the latest Omniguard Communications software from the Omniguard Software Downloads page.

If you have activated your service and have the correct version of firmware, make sure you have set up the modem correctly. Touch the modem icon on the home screen. If there are any errors reported, fix those first. On the modem setup screen make sure you have entered the email addresses correctly and checked status and/or log for each one. On the options page make sure you have selected the status messages you would like to receive and set the log time correctly (it is 24 hour time). When everything is set up use the "Test" button to make sure it is working properly.
