NOTE
The three keys on the keypad are assigned to the key references displayed
above them in the second line of the display as follows:
Key C: When pressed, shows the number of flushes
Key F: When pressed, triggers manual flushing
Key Q: When pressed, acknowledges the alarm messages
3.1.1 Master switch operation feedback contact
When the master switch is in the "On" position, a contact is made.
3.1.2 Control voltage monitoring
As soon as the master switch is actuated, the power supply is activated and the
controller is working properly, the green "Operation" LED lights up and the
"Control voltage monitoring" relay is activated. In the event of operating voltage
failure or a fuse fault on the control circuit board, no LED lights up and the
"Control voltage monitoring" relay is no longer activated.
3.1.3 Motor fault
If the measured motor current exceeds the set setpoint value for parameter P9,
a message appears in the display and a potential-free signal is sent to the relay
outputs. The motor and the backflushing function switch off immediately. Once
the fault has been remedied, the user has to acknowledge the alarm message by
pressing the Q key.
3.1.4 Differential pressure too high, flushing oil treatment cartridge alarm
The signal transmitter is a pressure switch contact which is connected to the
"Differential pressure indicator DP too high flushing oil treatment" optocoupler
input. If the message is active for a longer period than the time set in parameter
P7, an alarm message appears in the display. Once the fault has been remedied,
the user has to acknowledge the alarm message by pressing the Q key.
3.1.5 DP - too high, backflushing filter (100 %)
The signal transmitter is a pressure switch contact which is connected to the
"Differential pressure indicator DP too high, backflushing filter" optocoupler input.
If the message is active for longer than 2 seconds, an alarm message appears
in the display screen and the red "Alarm" LED lights up. Once the fault has been
remedied, the user has to acknowledge the alarm message by pressing the Q
key.
3.1.6 Key C (number of flushes)
When key C (number of flushes) is pressed, the number of flushing cycles which
have been performed is shown on the display screen for 3 seconds.
3.1.7 Multiple flushing
The number of parameterised chambers is worked off with each flushing
command.
