The printer symbol will be displayed with a JAM message (see
Section 4: Turning Printer On/Off). After the paper jam is cleared,
use the PRINTER ON/OFF key to turn the printer back on.
Note: Do not apply oil or grease of any kind to the printer as this will
attract dirt and debris and could cause permanent damage to the
printer mechanism.
Problem: OMNIGUARD 4 unit does not enter normal operation
when turned on, and does not print.
Remedy: For normal operation, the monitored pressure must be
between the Alarm 1 and Alarm 2 setpoints. When the unit is
first turned on, the containment pressure will not likely be within
the alarm setpoints, and the unit will not print or log the pressure
readings. The unit will begin printing and logging the pressure
readings only after it senses containment pressure has reached
the normal operating window.
Problem: The unit displays Date & Time Not Set followed by
Factory Default after the power has been off.
Remedy: The internal clock battery is discharged. Leave the unit
plugged in for 24 hours to recharge the battery. It will be necessary
to update the Date and Time settings. The internal battery lasts
for an average of 30 days without recharging. It recharges
automatically any time the unit is plugged in. No other settings
need to be re-entered (they are saved in non-volatile memory and
do not require the internal clock battery).

Problem: The unit does not display the proper pressure.
Remedy: Check to see that the tubing is connected properly to the
INLET 1 port. The INLET 2 port should not be connected.
Remedy: Make sure that the tubing does not have a kink or a sharp
bend.
Remedy: Make sure that you are using the correct 3/16” ID tubing
size, and the end of the tubing on the inlet nozzle is not worn. If
it is worn or loose, cut off 1” of the tube using a sharp knife and
reinsert on the inlet nozzle.
Remedy: Make sure that the tubing connection into the containment
area is properly placed and secured as described in Section 4:
Work Area Setup.
Problem: Excessive momentary alarms.
Remedy: Adjust alarm setpoints to allow for normal air pressure
fluctuations caused by entries into work area or other equipment.
Make sure that you are within the minimum negative air pressure
requirements.
Remedy: If you suspect that wind may be causing rapid pressure
fluctuations, reduce the setting for Response Rate (see Section
4: Detailed Operation).
Problem: Printer indicates an alarm but audible alarm was not
activated.
Remedy: Confirm that the Audible Alarm is on. The buzzer icon should
be shown, in the right corner of the display, without an X through
it (see Section 4: Alarm Silence , Disable and Rearming).
Problem: Printer is not working properly or a paper jam occurs.
Remedy: The printer may be turned off. Turn it on using the PRINTER
ON/OFF key.
Remedy: Thermal paper prints on one side only, the side away
from the paper roll. If installed incorrectly, the printer will be able
to advance the paper but unable to print on it. Make sure that
the paper is fed properly as described in Section 3: Loading the
Thermal Printer Paper.
Remedy: Paper jams can occur if the paper is allowed to fall back into
the printer head after tearing off a report. If a paper jam occurs,
the unit will automatically shut the printer off to prevent damage.
