Whenever power is interrupted to unit (i.e., unplugged, main disconnect switch off, kill switch
depressed), power must be restored by correcting power interruption condition and pressing
green
start button.
Corrective Action
A. Turn Main Disconnect Switch to ON position.
B. Check input cord(s) for proper connection to power source.
C. Check power source for proper voltage.
D. Open Main Control Box lid and check voltage with multitester
at voltmeter terminals. Replace defective voltmeter.
E. On single input, 240volt/60hz. units, check for proper wiring
of four prong plug and connector body.
A. Check voltmeter. If no voltage, refer to #1 above.
B. Check power on
both
input cords. (double input machines)
C. Check indicator tab on the top of the dropout relay. If tab is
out, relay is not engaged. If tab is in, relay is engaged. On
double input machines, check the dropout relay on the top
(C3). (If tab is "in", refer to #3.)
A. Check transformer breaker (breaker#1) (Green, breaker is
tripped. Red breaker is OK.)
B. Check secondary output of transformer (24volt). Replace if
necessary
A. Check for proper start-up conditions as mentioned at
beginning of this section. (See #2)
B. Be sure remote control cord is properly plugged into Main
Control Box.
C. Check remote control cord and hand pendant switch for
damage or loose connections.

inspect system for defective, broken or loose wiring connec-
tions inside blower box.
E. Check blower breaker(s) in Main Control Panel. (Green,
breaker is tripped. Red breaker is OK.)
F. Check Blower Controls. Disconnect Blower Control wires
on Main Control Panel door and reconnect the two power
leads bypassing the Blower Control. (Blower will run full
speed only.)
G. Visually inspect and/or replace blower relay (C5) inside
Main Control Panel.
2) Dropout relay
