DIN PLUG ISSUES
POSSIBLE SOLUTIONS/ ADVICE
Incorrect wiring.
• Check wiring diagram to confirm that the right cable is connected to the right pin.
• The power connection is grey (pug and base) with neutral in pin 1 and a switchable live between pins 2 (to close) and 3 (to open),
• The end of travel confirmation (black plug & base) is live on pin 1 and neutral on 2 and 3.
• NEVER connect the grey plug to the black base or vice versa, otherwise short circuits will irreparably damage the actuator. Such
damage is not covered by the warranty.
• The DIN plug base is marked with the pin numbers, and the plugs (and bases) are colour coded.
• The stripped part of the cable is too long and can touch and short with other pins.
• Cable gauge too big for size of connector
• Trapped cables when plug cover replaced
• Cables damaged when securing screw re-inserted when cover replaced (usually occurs when cables are trapped under cover on re-
assembly)
• DIN plug seals not fitted, or if profiled seals, fitted the wrong way round.
• Securing screws over-tightened, under-tightened, or not fitted at all.
• Cable gland (strain relief) not fitted, or incorrectly fitted can allow water ingress/ condensation. Also, small gauge (outside diameter)
cable can eliminate the effectiveness of the cable gland, again allowing ingress/ condensation.
• If the DIN plugs are knocked the bases can come away from the housing – ingress protection is lost.
