Error Error message text Cause Remedy
10 The mA input current
is too low
The power circuit is discon‐
nected
Check the 2-wire connection between
the sensor/transmitter and controller
and check the raw value in mA by
pressing . If the value is 0 mA, then
the connection is disconnected
11 After elapse of the
delay period, a limit
value error still exists.
The measured value lies
above the limit value for a
period longer than the set
delay period
Check whether the choice of the limit
value matches the application and
adjust the limit value if necessary.
Check whether the choice of the delay
period matches the application and
adjust the delay period if necessary.
Check the design of the actuator. Is
the actuator selected too large?
Check the concentration of the
metering chemical – is the concentra‐
tion too high?
Check the control parameters. Does
the control tend to over/undershoot?
12 There is a sample
water fault e.g. no flow
The in-line probe housing's
sample water limit contact e.g.
DGMa was triggered by the
float dropping.
Check the routing of the sample water
line
Check the sample water discharge
point. Is it blocked?
Check if a sample water filter is fitted
and clean it if necessary
13 The controller is in
‘Pause’ mode
The Pause input (digital input)
was activated externally
Check whether the Pause signal
received matches the system's
expected operating mode.
Check whether the
‘NO/NC’ actuating
direction matches the choice in the
controller.
14 The controller is in ‘
Pause (Hold)’ mode
The Pause input (digital input)
was activated externally
Check whether the Pause signal
received matches the system's
expected operating mode.
Check whether the
‘NO/NC’ actuating
direction matches the choice in the
controller.
15 The mA input supply is
overloaded
The sensor input of channel 1
or 2 is used in 2-wire connec‐
tion mode, e.g. together with
chlorine sensor CLE3.
The polarity was not noted or
there is a short circuit between
the two poles.
Check the polarity against the terminal
diagram.
Make sure that the two wires do not
touch (shorten the bared length, use
insulated end sleeves, use heat-shrink
tubing)
16 The mA input is over‐
loaded
The sensor input of channel 1
or 2 is used in 2-wire connec‐
tion mode, but the signal is an
active signal carrying voltage.
Use a multimeter to check the meas‐
uring signal. If it is an active / driven
signal (voltage is measurable), then
the type of connection has to be
selected for active signals, refer to the
terminal diagram in the operating
instructions. This type of connection is
not shown on the enclosed terminal
assignment diagram.
