Remedy
Software error: Reboot system, if error still present:
Re-copy system software on VSM, replace control
module PCB
Replace O
measuring sensor
2
Check continuity of connection cable, replace if necessary
Check mains voltage, if mains voltage is out of tolerance,
changeover transformer connections accordingly.
Check interconnecting cable to DMM, replace if necessary
Check voltage supply
Replace control module PCB
Replace measuring bank
Replace measuring bank
Replace measuring bank
Check coarse filters GF1, GF2, GF3 and GF4,
replace if necessary
Check suction power of pump, replace if necessary
Check flow sensor, replace if necessary
Check hosing as per gas circuit diagram
Clean condensate separator
Replace measuring bank
Perform recalibration with calibrating gas
Replace measuring bank
Replace carbon canister
Check cross sensitivity to water vapour
Replace hosing as per gas circuit diagram
Clean analyzer chambers, not in warranty cases!
Replace measuring bank
Check exhaust-sample probe and hose for cracks
Check hosing as per gas circuit diagram
Perform leak test of measuring bank, replace
measuring bank if necessary
Purge exhaust-gas analyzer module with fresh air,
if error still present: replace internal hosing (see gas
circuit diagram)
