FORM 160.52-PW1 NOTES:

1.This wiring diagram describes the standard electronic

control scheme for use with an electromechanical starter.

For details of standard modifications, refer to Product Form 160.49-PW13.

2.Field wiring to be in accordance with the National Elec-

trical Code as well as all other applicable codes and specifications. See Product Form 160.49-PW10 for field wiring connections.

3.Numbers along the left side of diagram are line identifica-

tion numbers. The numbers along the right side indicate the line number location of relay contacts. An underlined contact location signifies a normally closed contact.

4.Main control panel Class 1 field wiring terminal connec-

tion points are indicated by numbers within a rectangle,

i.e. 15 . Main control panel factory wiring terminal con-

nection points are indicated by numbers within a triangle,

i.e. 5 . Component terminal markings are indicated by

numbers within a circle, i.e. C1 . Numbers adjacent to circuit lines are the circuit identification numbers.

5.To cycle unit on and off automatically with contacts other

than those shown, install a cycling device between ter-minals 1 & 13 (line 37) (see note 9). If a cycling device is installed, jumper must be removed between terminals

1 & 13 .

https://www.wendangku.net/doc/299857849.html,pressor motor starter with starter interlock contacts

(rated 0.5 to 1.0 amp @ 24 volts A.C.) must be per Form 160.45-P A5.1. Control panel shall be grounded.

7.Units installed in Canada must have a field supplied

CSA approved 30 Amp disconnect switch and a 20 Amp dual element fuse mounted external to control panel for 115 volt control supply.

8.To stop unit and not permit it to start again, install a stop

device between terminals 1 & 8 (Line 33) (see note 9).

A remote start-stop switch may be connected to termi-

nals 1 , 7 & 8 (Lines 32 & 33) (see note 9). Remote start-stop switch (Line 32) is operative only in the “re-mote” operating mode.

9.Device contact rating to be 5 milliamperes @ 115 volts

A.C.

10._____________

11.Contact rating is 5 Amp resistive @ 120 volts A.C. or

240 volts A.C.

12.Three phase oil pump must be properly phased L1, L2

& L3 corresponding to phase sequence A, B & C. 13.To check motor rotation on initial start-up, install mo-

mentary switch between terminals 24 & 25 (line 41).

Depress start switch. After approx. 30 seconds, jog mo-tor with momentary switch. When proper rotation is ob-tained, replace momentary switch with jumper. Switch must have a minimum contact rating of 2 FLA., 10 LRA at 115 Volts A.C.

14.Motor overload (CM) is set to trip at 105% FLA. During

momentary power interruption (power fault), contact opens for 1 second.

15.For high and low voltage units, the factory supplied

jumper between 1 & 53 must be removed when elec-tromechanical starter overloads and/or safety devices are used. For high voltage (2300-4160) UL and CUL approved units only, electromechanical compressor motor starter overloads (normally closed) must be con-nected between 1 & 53 .

16.Contact rating is 5 Amps resistive @ 250 Volts A.C. & 30

Volts D.C., 2 Amp inductive (.4 PF) @ 250 Volts A.C. & 30 Volts D.C.

17.Each 115VAC field-connected inductive load: i.e. relay

coil, motor starter coil, etc., shall have a transient sup-pressor wired in parallel with its coil, physically located at the coil. Spare transient suppressors and control cir-cuit fuses are supplied in a bag attached to the top of the hinged panel.
