Operation
700 P electronics module
6.
Limit value ?
Cl2++ ?
pH<6 or pH>8.75
pH measurement is not available.
Check the pH measurement, check
DFMe electronics module, check
CAN bus setup.
Cl2 combined ?
Free Cl
2
measurement is not avail-
able.
Check the DFMe electronics mod-
ule, check CAN bus setup.
Overfeed ?
The maximum dosing time set for a
control output has been exceeded.
Determine the cause, e.g. chemical
tank empty.
Check the dosing pump.
Adaption ?
Adaption terminated with error.
See Chapter 3.4.10 “Adaption (only
applies to free Cl2)”.
CAN measuring value
?
No CAN bus subscriber.
Check CAN bus, set parameters for
CAN subscribers.
Temperature ?
Interruption in the temperature sen-
sor or cable of the multi-sensor.
Check multi-sensor and cable.
Sample water ?
Positioner Ym ?
Ym range too narrow.
Positioner position incorrectly cali-
brated.
Check the gap between the calibra-
tion points.
Positioner selected, but not con-
nected.
Check setting: Positioner with Ym.
Feedback signal incorrectly set.
Check DIP switch for feedback.
Positioner feedback incorrectly con-
nected or defective.
Check (refer to 9. “Wiring Dia-
grams”).
Calibration Ym ?
Positioner calibration incorrect.
Check calibration of actuator feed-
back.
mA output 1 ?
mA output 2 ?
mA output 3 ?
mA output 4 ?
Load error
The mA output cannot drive its mA
output current through the con-
nected current loop (500 Ohm at 20
mA max.).
Check whether the mA signal is
required at all (e.g. for plotter). If not,
switch off the output signal in the
“INPUTS/OUTPUTS” menu, “Ana-
log output”.
Check mA signal cable for interrup-
tion
Flocculation ?
pH value outside the flocculation
limit values.
Check flocculation limit values.
Check pH measurement and con-
trol.
