Cause Remedy
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 over‐
loaded
The sensor input of
channel 1 or 2 is used in
2-wire connection 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
overloaded
The sensor input of
channel 1 or 2 is used in
2-wire connection mode,
but the signal is an
active signal carrying
voltage.
Use a multimeter to check the
measuring 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 ter‐
minal assignment diagram.
17 The level in the
storage tank 1 is
too low
The chemical in storage
tank 1 is used up
