Installation
• Make the connection at the switch end first. This way you can
check continuity at the dryer end before connecting to the
dryer. Make sure that the contacts on the switch are normally
closed. Pin 1 of the dryer EM connection puts out a 5 VDC
signal. Take care to ensure that the contacts on the switching
device are 'dry' and free of any voltage which could harm the
dryer controller.
• Locate the DIN connector on the base of the controller.
• Remove the screw completely from the centre of the
connector.
• Remove the blanking plug from the connector and discard
• Insert a small flat screwdriver into the small recess at the edge
of the insert, pry the insert out of the DIN connectors outer
shell (Figure 7.7).
• Remove the jumper wire which is between pins 1 and 2 and
discard.
• Slip cable end through DIN connector's cable gland and out
through the front of the DIN connector.
• Strip the outer insulation of the cable back approx 3/4"
(20mm).
• Strip the conductor insulation back approx 1/8" (3mm).
• If possible using a meter, check the continuity between the
two wires to ensure that the switch is in a closed position. If
it is possible to verify the switch function as well this may be
helpful.
• Insert conductors into pins 1 & 2 of insert. Tighten retaining
screws securely.
• Determine which direction the cable gland should point.
• Carefully pull the cable back through the shell until the insert
snaps back into place. Take care to work the wires around the
retaining screw hole as they can become fairly easily pinched.
• Plug the DIN connector back onto the dryer's EM connection
taking care to make sure that sealing gasket is in place.
Note: The male ground pin is slightly wider than pins 1 & 2.
Take care to ensure that the female connector is oriented
correctly.
