1.
POWER SUPPLY - AN ADEQUATE POWER SUPPLY AND PROPER WIRING ARE
IMPORTANT FACTORS FOR MAXIMUM PERFORMANCE AND LONG DRYER LIFE. ELECTRICAL
SERVICE MUST BE OF ADEQUATE SIZE TO PREVENT LOW VOLTAGE DAMAGE TO MOTORS
AND CONTROL CIRCUITS. SEE TABLE 2.1 FOR FULL LOAD AMPS PER DRYER MODEL.
NOTE: ALL MOTORS ARE EQUIPPED FOR 230V SINGLE (1)PHASE, 208V, 240V,
380V, 415V, 480V OR 575V THREE (3)PHASE OPERATION. WHEN ONLY 230V SINGLE
(1)PHASE POWER IS AVAILABLE, A PHASE CONVERTER MAY BE INSTALLED AHEAD OF
DRYER TO OBTAIN THREE (3)PHASE POWER TO OPERATE 240V OR 480V THREE (3)PHASE
DRYERS.
2. POWER SUPPLY DISCONNECT - ALL DRYERS SHOULD BE EQUIPPED WITH A
POWER DISCONNECT SWITCH AHEAD OF DRYER CONTROL BOX TO PERMIT TOTAL POWER
SHUT DOWN BEFORE OPENING CONTROL BOX, AS REQUIRED FOR INSPECTION AND
SERVICE. THE POWER DISCONNECT SWITCH SHOULD ALSO BE LOCATED CLOSE TO THE
DRYER FOR QUICK SHUT DOWN.
3.
ELECTRICAL PHASING - FOR YOUR CONVENIENCE YOUR DRYER HAS HAD ALL
MOTORS PHASED. IF ONE MOTOR RUNS BACKWARDS, THEY ALL WILL. SIMPLY CHANGE
THE TWO MAIN WIRE LEADS AROUND AT MAIN TERMINAL CONNECTION BLOCK FOR PROPER
ROTATION.
(NOTE: CONTROL DESIGN REQUIRES WILD LEG TO BE CONNECTED TO
TERMINAL "L2" ON 240V THREE (3)PHASE DRYERS).
4.
CONNECTING AUXILIARY CONVEYORS - AUXILIARY STARTING EQUIPMENT IS
SUPPLIED AS STANDARD EQUIPMENT. REFER TO DRAWING FOR PROPERLY CONNECTING
AND INTERLOCKING WET LOADING AND DRY UNLOADING AUXILIARY STARTING EQUIPMENT
LOCATED IN THE ELECTRICAL CONTROL PANEL. MAKE CERTAIN THAT THE MOTOR
OVERLOAD PROTECTION MATCHES THE MOTOR BEING USED.
5.
IMPORTANT:
1. MAKE SURE DRYER IS PROPERLY GROUNDED. GROUND LUG IS
PROVIDED.
2. HAVE THE POWER COMPANY OR YOUR LOCAL ELECTRICIAN CHECK
LINE VOLTAGE AND AMPERAGE.
MAKE SURE VOLTAGE DROP IS
MINIMUM.
