8.1.3 Instrument-specific error
No cleaner conveyance – Tank empty
– Line blocked Check error messages.
Test functions in manual operation. Indicator LEDs CPG30
(see fig. 35 / fig. 36, page 39):
V1 : Additional valve 1 active
Meas : Assembly in measurement mode
Alive : LED flashes irregularly, if function
o.k.
Pressure switch feedback (Pos.No. 440,
p. 136) type "active open":
no pressure = closed
with pressure = open.
Assembly stays in
"Service" position – No compressed air
– Switch to "Maintenance"
– Incorrect position feedback signal
Check error messages
Test functions in manual operation.
Disconnect pressure switch and check with
Ohmmeter.
Assembly stays in
"Measurement" position
– No compressed air
– Switch to "Measurement"
– Incorrect position feedback signal
Assembly permanently
proceeds Pneumatic hoses to assembly connected
in a wrong way Check pneumatic hoses.
Assembly proceeds several
times without correct
feedback – Pneumatic connections interchanged
– Feedback not correctly connected
– Feedback switch is wrongly adjusted
– Assembly has been proceeded
manually. Feedback signal is,
therefore, undefined.
– fig. 29, page 34 or fig. 32, page 36 and
fig. 53, page 139:
Hose 2 "measuring" to valve 5 in front,
hose 3 "service" to valve 5 in the back.
– fig. 29, page 34 or fig. 32, page 36 and
fig. 53, page 139:
Hose 5 "measuring" feedback
(terminals. 11/12), hose 6 "service"
feedback (terminals 13/14)
– Feedback switch under pressure:
opened: Kl. 11/12-13/14 = 14 V
closed: Kl. 11/12-13/14 = 0 V

operation
Error Possible cause Remedial action Equipment needed, spare
parts
Error Possible cause Tests and / or remedial action Equipment, spare parts,
personnel
Display dark, no LEDs
active No mains voltage Check whether mains voltage is applied. Electrician / e.g. multimeter
Supply voltage incorrect or too low Compare actual mains voltage with
nameplate rating.
Connection defective Terminal not picked-up; insulation clamped.
Instrument fuse defective (non-Ex) Replace fuse after comparing mains voltage
and nameplate rating. Electrician / suitable fuse; see fig. 49
(p. 135)
Instrument fuse defective (Ex) Replace fuse. Use Ex fuse; electrician required
Power unit defective Replace power unit, pay attention to variant. On-site diagnosis: all 6 red LEDs on the
M3G module must be lit
Central module defective (if all 6 LEDs
on the power unit M3G are lit) Replace central module.
Pay attention to variant. On-site diagnosis by responsible service
(test module required)
Ribbon cable loose or defective Check ribbon cable. Cable soldered onto the site of the M3G
module
Display dark, but
LED active Central module defective
(Module: M3Cx-x) Replace central module M3Cx-x. On-site diagnosis by responsible service
(test module required)
Display functioning, but no
change in display and/or
instrument cannot be
operated Instrument or module in instrument not
correctly installed Check module connections. See device view on page 135
Operating system in impermissible state Switch instrument off and on. Possibly EMC problem: if problem persists,
have installation checked by responsible
service
