The error is either from no open/close cycles of the reed switch, no motor movement, defective cabling or a defective controller. Test motor, reed switch, cable continuity and controller operation.
Motor Test:
Disconnect the heavier gauge M1 and M2 wires (White and Red) from the terminal block and apply 12 or 18Vdc from a battery to the Red and Black motor wires. Does the motor run and the actuator extend or retract? Reverse the leads to reverse the polarity. Does the motor run and does the actuator run the opposite direction?
Limit Switch Test:
If not, check the limit switch for continuity. If the limit switch plunger is extended (not pushed in by the adjustable travel limit wheel), it should be a closed circuit and pass motor power. When the limit switch plunger is depressed by the travel limit wheel, the circuit is opened and only allow travel in the opposite direction.
Reed Switch Test:
Disconnect the control cable's Orange and Green/Shield Drain wires from the terminal and place an ohm meter on the two white color wires from the reed switch. Run the motor actuator both directions using a 12 or 18Vdc battery as described above. Do you observe the reed switch open and close cycles as the motor runs? If the circuit remains open or closed, the reed switch or jumper wires are defective. If erratic cycles, the reed switch may have become magnetized because of years of inactivity parked on the magnet. Contact Von Wiese for a replacement reed switch or DYI a reed switch assembly from DigiKey or ???
Controller Test:
Attach voltage meter (Vdc 50 volt range) leads to the controller M1 and M2 terminals. Power ON the controller and tap East or West button. Do you observe a momentary Vdc reading before the error message appears? If so, likely the controller is outputting motor control voltage for that direction of travel. Remove and reapply power to clear he error message and repeat the test by pressing the opposite direction button. Do you observe momentary Vdc reading before the error message appears? If so, likely the controller is outputting motor control voltage for that direction of travel.
Testing the sensor count is more difficult, but might be accomplished by rapidly tapping wires attached to the controller S1 and S2 terminals while pressing the East or West motor button. I have quickly tapped a CW key to emulate the switch cycles.
