FIG. 5 – DISPLAY INTERFACE BOARD
NOTES: 1. This wiring diagram describes the standard elec tron ic
con trol scheme for use with a YORK V.S.D. for details of standard modifi cations, refer to Product Form 160.54-PW7.
2. Field wiring to be in accordance with the National Elec tri cal Code as well as all other applicable codes and spec i fi ca tions. See Product Form 160.54-PW6 for fi eld wiring con nec tions.
3. Numbers along the left side of diagram are line iden ti -fi ca tion numbers. The numbers along the right side in di cate the line num ber location of relay contacts. An un der lined con tact lo ca tion signifi es a normally closed con tact.
4. Main control panel Class 1 fi eld wiring terminal con- nec tion points are indicated by numbers within a rect an gle, i.e. 15 . Main con trol panel factory wiring terminal con- nec tion points are in di cat ed by numbers within a tri an gle, i.e. 5 . Com po nent terminal markings are in di cat ed by num bers within a circle, i.e. C1 . Num bers ad ja cent to cir cuit lines are the cir cuit iden ti fi ca tion num bers.
5. To cycle unit on and off automatically with contacts oth er than those shown, install a cycling device between ter mi nals 1 & 13 (line 37) (see note 7). If a cycling device is installed, jumper must be removed between ter mi nals 1 & 13 .
6. To stop unit and not permit it to start again, install a stop device between terminals 1 & 8 (Line 33) (see note 7). A re mote start-stop switch may be connected to ter mi nals 1 , 7 & 8 (Lines 32 & 33) (see note 7). Remote start-stop switch (Line 32) is op er a tive only in the “re mote” op er at ing mode.
7. Device contact rating to be 5 milliamperes @ 115 volts A.C.
8. Contact rating is 5 Amps resistive @ 120 volts A.C. or 240 volts A.C.
10. For wiring diagram of V.S.D refer to product form 160.49-PW9.
11. A jumper is installed between terminals 24 & 25 for normal operation.
CAUTION: The jumper is the only connection permitted between terminals 24 & 25 . Connections of any other devices to either terminals 24 & 25 may cause inadver-tent compressor start-up.
12. Stop contact on V.S.D logic board is set to trip at 105% FLA.
13. 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.
14. Field connected control power supply is not required, as control transformer is supplied on the V.S.D.
15. For high and low voltage units, the factory supplied jumper between 15 & 53 must be removed when elec-tromechanical starter overloads and/or safety devices are used. For high voltage (2300-4160) UL and CUL ap-proved units only. Elecromechanical compressor motor starter overloads (normally closed) must be connected between 15 & 53 .
16. Each 115VAC fi eld-connected inductive load: i.e. relay coil, mo tor starter coil, etc., shall have a transient sup- pres sor wired in parallel with its coil, physically located at the coil. Spare tran sient suppressors and control cir cuit fuses are sup plied in a bag attached to green ground screw in lower left corner of control panel.
17. Resistor for use with Belimo actuator. Remove resis-tor if hot gas actuator is a Dodge Engineering, Bray or Landis-Staefa actuator.
