Question 1

Error PCB Over heat: PCB Over heat

Accepted Answer

Take the isolation key out and wait 5 minutes to give the thermal fuse a chance to reset - the red light should no longer flash, and the electronics control box shouldn't be hot to the touch.

Question 2

Error Low Caravan Battery Voltage: Low Caravan Battery Voltage

Accepted Answer

Check voltage of battery, charge or renew caravan battery.

Question 3

The unit's completely dead and won't operate at all

Accepted Answer

Reset the electronics control box: switch off, take the isolation key out for at least 20 seconds, then switch back on. The green light on the box should then be lit.

Question 4

The unit's completely dead and won't operate at all

Accepted Answer

Check the in-line fuse hasn't broken and that 12V DC is actually reaching the ECB.

Question 5

The unit's completely dead and won't operate at all

Accepted Answer

Reset the isolation switch: turn it off, take the key out for at least 20 seconds, then switch back on - the electronics box's green light should then light up.

Question 6

The unit's completely dead and won't operate at all

Accepted Answer

Give the ECB 5 minutes to let the thermal fuse reset itself, and check the ECB isn't feeling hot.

Question 7

The unit won't operate, or operates on and off

Accepted Answer

Confirm the handset battery reads the correct 9.5V. If, on switching the handset on, all 6 red LEDs give two flashes, that's also a sign the handset battery is low - you can also check this using the emergency umbilical cable.

Question 8

The unit won't operate properly, or moves in a stop-start way

Accepted Answer

Possible cause: Radio interference. Test using the emergency umbilical cable.

Question 9

The unit won't operate properly, or moves in a stop-start way

Accepted Answer

Possible cause: The battery terminals are poorly connected or corroded. Clean the battery terminals and make sure they're properly connected.

Question 10

The unit won't operate properly, or moves in a stop-start way

Accepted Answer

Possible cause: Caravan battery low. Check the caravan battery's voltage with nothing switched on, at least 4 hours after it was last charged: about 12.7V or more is fully charged, 12.4V is roughly half, and 12.0V or less is flat. Charge or replace the battery as needed.

Question 11

The caravan won't move, or only moves on and off

Accepted Answer

Possible cause: Caravan battery low. Engage the rollers, move the caravan, and check how far the caravan's battery meter drops - if it drops below 12V, have an accredited supplier test the battery, then charge or replace it as needed.

Question 12

On manual operation, the roller won't disengage or engage even though the hex shaft turns fully

Accepted Answer

Call Powrtouch Technical Department.

Question 13

On electrically-actuated units (Powractuation fitted), the roller won't disengage

Accepted Answer

Put the handbrake on. Holding button E down, press the H direction-arrow button, then release both at once. The handset's LED speed meter counts down from four to one, then the actuators run and the red LED under button H flashes; check the rollers are clear of the tyres before towing. (Pressing D or F stops the actuators immediately if they were started by mistake.) If a motor or system fault stops the rollers retracting, they can be wound off by hand, depending on the motor fitted. Motor System 1: on the back of the small Powractuator motor, remove the rubber top-hat cover, then wind the 9mm nut beneath it anti-clockwise - because of the reduction gearbox this takes a lot of turns, so a cordless drill or screwdriver helps. Motor System 2: push the 'tool for hand removal' supplied with the Powrtouch into the hole on the back of the motor, which gives you a 10mm nut to turn in the same way. If in doubt, ask a qualified Powrtouch engineer.

Question 14

Rollers slip on wheels

Accepted Answer

Disengage the rollers and check the gap to the tyres - 15mm on large-roller versions, 20mm on small-roller versions - and check the tyres aren't badly worn or incorrectly pressured.

Question 15

Rollers slip on wheels

Accepted Answer

Check the roller-to-tyre distance - 15mm for large-roller versions, 20mm for small-roller versions - and confirm tyre pressures are correct and the tyres aren't badly worn.

Question 16

Unit fails to operate

Accepted Answer

Check the handset's battery voltage is correct - a slow-flashing green light on the handset is one sign it isn't. You can also check this with the emergency cable, but always take the handset battery out first when using it.

Question 17

Roller will not engage, spindle rotates fully.

Accepted Answer

Possible cause: Safety spirol pin broken. Safety spirol pin broken, call factory.
