How to calibrate / adjust circuit board WRC1021D after replacing circuit board and/or change of feedback potentiometer on winch.

NOTE:Make sure that all main pumps are OFF and servo-pump is ON during calibration/adjustment of WRC card.

1. Calibration of control lever on winch.

Make sure that all control levers are standing in correct stop position. Activate dipswitch number 8 on WRC card. Operate the control lever on winch to full hoist and then to full lower. Operate joysticks on bridge panel to full hoist and then to full lower. Operate joysticks on deck panel, if present, to full hoist and then to full lower. Deactivate dipswitch number 8 on the WRC card to store the calibration values into the card.

2. Calibration of dead band.

The dead band value is adjusted using pot meter number 5 on the WRC card. Clockwise adjustment will result to a bigger dead band. Counter clock-wise adjustment will result to a

smaller dead band. If the control lever on the winch won’t settle in stop position, adjust the dead band clock-wise.

3. Adjustment of full hoist position in ”auto” mode.

Use dipswitch number 7 to activate the ”full hoist” mode on the WRC card (dipswitch number 7 activates the WRC card in the same way that a full hoist signal from the control system). Adjust full hoist on the winch control lever by using pot meter P1 on the WRC card. Turn dipswitch number 7 ”off” when the “full hoist” position is properly adjusted. Use pot meter P2 to adjust the control lever movement time from ”stop” to ”full hoist” position when “full hoist” command is activated. Adjust the control lever movement time to approx 10 seconds.

4. Activating “Creep drive” function.

On anchor handling and towing winches the last few years, the function “creep drive” is implemented to avoid damage on gear during coupling in. Activate dipswitch number 5, and make sure that P2 is adjusted as described in above chapter. Adjust movement time to approx 10 seconds.

5. Digital output channels on WRC card.

On winch deliveries during the few last years, there are mounted valves that lead some of the oil around the winch manoeuvre valve and directly into the motor. These valves, together with other valves on pipe- and pump-arrangement, are partly controlled from the WRC 1021 circuit board.
