Installing the 506/507/508
506/507/508 - HA389427
Note:
Even when intending to utilise tachogenerator feedback it may
be wise to initially run under armature control. Set feedback
voltage switches accordingly. Note that if this procedure is
followed the tachogenerator must be temporarily disconnected
as it will affect operation of the controller.

Motor
(a) Check motor is compatible with controller and settings.
(b) Check motor and load are free to rotate.
Wiring
(a) Check there is no loose wire ends on the PCB.
(b) Check that there are no free wire ends on external controls
liable to contact grounded metal or earth (ground) referenced
parts.
Applying Power
1. Power on LED 1 should illuminate.
2. Close “RUN” contact and apply a small speed setpoint (5%).
Armature current should now flow, the motor should turn and run at
a fixed speed.
If the motor runs above 5% up to top speed Open Run Contact.
If the controller is in “Armature” Control then excess speed is due to
incorrect setting of SW2 and 3, the speed scaling.
