Circuit Board CB016BP-7
Doc/FC/1168-01
If the motorised roller is blocked by a load that has jammed in the frame for example, it will attempt to free the load. After 4 seconds, if
the motorised roller is still blocked, it will stop and the circuit board will switch to default.
The combination of LED 2 – red and LED 3 – orange provides diagnostic detail of the type and the number of errors.
See table under title: E r r o r I d e n t i f i c a t i o n
When restarting the motorised roller after thermal protection activation, terminal 1 (Run/Stop) or 2 (Direction) on the CN2 connector
must only be signalled after eliminating the cause of the fault (freeing the blockages, allowing the cooling of the thermal protection.
The voltage supply to the circuit board must be switched off in order to initialize the fault history shown by LED 3 (orange)
Do not exceed 10V to vary the speed by analogue voltage
Mount the entirety of the circuit board’s aluminium back plate onto a metal surface in order to guarantee good thermal
dissipation.
A regulated power supply is essential
Use a sufficiently sized/rated power supply according to the number and type of motorised rollers. The absorbed current
depends on the model and the speed code of the motorised roller.
Do not to unplug the motor connector while the motor is running.
Eliminate the cause of thermal protection activation for frequent error signals
Do not stop the Power Moller® 24 by interrupting the power supply to the circuit board. It is imperative that terminal 1
(Run/Stop) on the CN2 connector is used.
Do not change the direction of rotation while the motorised rollers are running. First stop the motorised roller and then change
the direction of rotation.
Make sure that the power supply is switch off before connecting or disconnecting the motorised roller
Leave a minimum of 1s after the circuit board is powered before starting the motorised roller for the first time.
Link the 0V together when varying the speed by an external analogue voltage 0-10V
Wire all other electrical connections in accordance with best codes of practice.
