Verifying Pump Operation

Users can check operation of the sampling system any time during operation by blocking the sampling
system to generate a pump alarm.
When the pump inlet, sample line or probe is blocked, the pump alarm must activate.
Once gas readings are displayed, plug the free end of the sampling line or probe.
-
The pump motor shuts down and an alarm sounds.
-
PUMP ERROR will flash on the display.

Press the  button to reset the alarm and restart the pump.
If the alarm does not activate:
-
Check the sample line and probe for leaks.
-
Once leak is fixed, recheck pump alarm by blocking the flow.

Press the  button to reset the alarm and restart the pump.
Do not use the device, sample line, or probe unless the pump alarm activates when the flow is
blocked. Lack of an alarm is an indication that a sample may not be drawn to the sensors, which
could cause inaccurate readings. If a sample line or probe is installed and the pump alarm does not
activate, remove the line or probe and repeat the test. This will provide information on where the
blockage is located.
Failure to follow the above can result in serious personal injury or death.
Never let the end of the sampling line touch or go under any liquid surface. If liquid is drawn into the
device, readings will be inaccurate and device could be damaged. We recommend the use of an
MSA sample probe containing a special membrane filter, permeable to gas but impermeable to
water, to prevent such an occurrence.
During operation, a pump alarm may occur when the:
-
Flow system is blocked
-
Pump is inoperative
-
Sample lines are attached or removed.
To Clear Pump Alarm
(1) Correct any flow blockage.
(2) Press the  button.
 The Pump will now restart.
