17.7 SYMPTOM: NO AUDIBLE TONE AT A CONTROL HEAD WHEN
POWER IS INITIALLY TURNED 'ON', BUT OTHERWISE, WORKS
PERFECTLY.
CAUSE
a) Incorrectly wired eight (8) conductor cable.
b) Defective sound transducer.
REMEDY
a) Insure that the black wire is connected to pin 1 in the Actuator,
and pin 1 at the control head. The brown wire must be
connected to pin 2 in the Actuator and pin 2 at the control head.
In addition, the LED would not work if the brown wire was loose
or incorrectly wired. Check for loose or corroded connections.
b) Measure the voltage at pins 1 and 2 of the control head (do not
depress the transfer button). The voltage should fluctuate at a
steady rate. If a fluctuating voltage is measured, replace the
control head or install a Control Head Repair Kit.
17.8 SYMPTOM: THE CONTROL HEAD LED DOESN'T LIGHT WHEN IN
CONTROL, BUT EVERYTHING ELSE WORKS PERFECTLY.
CAUSE
a) Incorrectly wired eight (8) conductor cable.
b) Defective LED
REMEDY
a) Verify that the brown wire is connected to pin 2 of the Actuator
and the control head.
b) Measure the DC voltage between pins 2 & 3 at the control
head. The reading will be 1.00 to 2.00 volts in normal
operation. If 4.00 volts is measured, the LED is OPEN. Replace
the control head or install a Control Head Repair Kit.
