Sample Gas Pump Control
Operation
The "Pump" push-button must always be pressed during operation (lights up
green).
The sample gas pump can be switched off with the "Pump" push-button, e.g. for
maintenance work.
Alarm
(only in the version with Peltier cooler)
The sample gas pump is switched off when
 a condensate alarm ("Alarm" LED next to the "Pump" push-button lights up
red) or
 a cooler temperature alarm ("K1" LED on the temperature controller is off)
is present. The "Pump" push-button continues to light up green.
After Power Failure
The jumper JP1 located on the circuit board can be used to set whether the
sample gas pump restarts automatically after a power failure:
Jumper in position 1–2: The sample gas pump does not restart (factory-set).
Jumper in position 2–3: The sample gas pump restarts automatically.
