Line open or short-circuited
Disconnect both (!!!) cables and measure
directly at the device.
mA meter 0–20 mA DC
Output defective Renew controller module.
No current output signal
Current outputs encoded as passive and
no additional power unit connected
Recode current outputs to active (see
"Wiring - Current output" section) or con-
nect power unit.
Jumpers for current outputs missing
Attach jumpers as per the desired encoding
(see "Wiring - Current outputs" section).
Fixed current output signal
Current output simulation on Switch off simulation. Check under "
Ð
> Service > Simulation".
Processor system inactive Switch device off and on again.
EMC problem: Check the installation if the
problem persists.
"Hold" is active Hold status, see display.
Incorrect current output
signal
Incorrect current assignment
Check current assignment:
0–20 mA or 4–20 mA?
See "Set up 1 - Current outputs" section.
Incorrect signal assignment
Every current output can be assigned to
every measured value (pH or temp).
Check under "
Ñ
> Current output"
Total load in the current loop too high
(> 500
Ω
)
Disconnect output and measure directly at
the device.
mA meter for 0–20 mA DC
Data cannot be saved No DAT memory module present
DAT available as accessory, see the
"Accessories" chapter.
CPG310 control unit not
working
No supply voltage Check connection
Fuse defective Check fuse and replace where necessary
Switch to "Service" Turn switch to "Measure"
No buffer and cleaner
pumped
Tank empty Check error messages
Test functions in manual mode Control LEDs CPG310:
V1: Additional valve 1 active
V2: Additional valve 2 active
Line blocked
MEAS: Assembly in measuring operation
Alive: LED flashes irregularly if function OK
Suction length longer than 2 m Reduce suction length to maximum 2 m
Feedback pressure switch (see item number
440 in "Spare parts" section), "normally
closed contact" type ("NC"):
Pump defective Check error messages Without pressure = closed
Multihose defective Test functions in manual mode With pressure = open
Compressed air or rinse
water are not pumped
Pressure reduced in the pipe Check pipe
Line blocked
Assembly remains in the
"Service" position
No compressed air
Check error messages
Test functions in manual mode
Control LEDs CPG:
V1: Additional valve 1 active
V2: Additional valve 2 active
Switch to "Service"
Disconnect pressure switch and check with
ohmmeter
MEAS: Assembly in measuring operation
Confirmation of position incorrect Alive: LED flashes irregularly if function OK
Assembly remains in the
"Measure" position
No compressed air
Feedback pressure switch (see item number
440 in "Spare parts" section), "normally
closed contact" type ("NC"):
Switch to "Measure" Without pressure = closed
Confirmation of position incorrect With pressure = open
Assembly constantly moves
Pneumatic hoses to assembly not
correctly connected.
Check pneumatic hoses.
