DIP SWITCHES

Cleaning

Cleaning function connected in ON position.
When the wheel has been still for 30 minutes, the cleaning function is 
activated and the wheel rotates for 20 seconds at 12 rpm.

Rotation monitor

Rotation monitor connected in ON position.

High speed *)

The wheel rotates at the set max. rpm when the switch is set to ON.

Low speed *)

The wheel rotates at the preset min. speed (1 rpm) when the switch is set 
to ON.

 *) Manual running (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, whatever the setting 
of the "Rotation monitor" DIP switch. 
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. 
The green light diode comes on with a fixed light for the first and second alarm and begins to flash on  
the third alarm. All alarms subsequently remain. 

Rotation monitor

Alarms and trips if a pulse is not received every 30 minutes at min.  
rotation speed (1 rpm) and every 20 seconds at max. rotation speed  
(350 rpm).  
The time between these speeds is linear.  
The function can be disconnected via DIP switches.
