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.
