DIP SWITCH
Blow-clean function
Blow-clean function connected in ON position.
When the rotor has been still for 30 minutes, the blow-clean function is
activated and the rotor rotates for 20 seconds at 12 rpm.
Rotation monitor
Rotation monitor connected in ON position.
High speed *)
The rotor rotates at the set max. rpm when the switch is set to ON.
Low speed *)
The rotor rotates at the preset min. speed (1 rpm) when the switch is set
to ON.
*) Manual operation (test mode)
OPERATIONAL INDICATIONS
On/Alarm
"Voltage on" comes on with a fixed light.
Flashes when the control unit has tripped.
Run
Comes on when the motor is to rotate, i.e. when the input signal exceeds
the threshold value.
Rotation
Flashes when the magnet passes the magnetic sensor, regardless of the
rotation sensor DIP switch setting.
Flashes even if the input signal is lower than the threshold value.
ALARMS
In the event of an alarm the control unit restarts after 30 seconds. The respective red light diode comes
on for the same duration (30 seconds).
After restart the light diode goes out, this happens twice. The third time, the alarm relay closes and the
alarm "moves on".
In order for the alarm relay to close and the alarm to "move on", the above three alarm signals must
occur within 90 minutes, otherwise the sequence is reset.
A steady green LED is activated for the first and second alarm and begins to flash on the third alarm.
All alarms subsequently remain active.
Rotation monitor
Generates an alarm and trips if a pulse has not been received every
30 minutes at minimum speed (1 rpm) and every 20 seconds at
maximum speed (400 rpm).
The time between these speeds is linear.
The function can be disconnected via DIP switches.
