Technical Guide

Start-Up & Commissioning

General

In order to have a trouble free start-up, it is important to follow a few

simple procedures. Before applying power for the ﬁ rst time, it is very

important to run through a few simple checks.

One of the most important checks to make before powering up the system

for the ﬁ rst time is to make sure that the VCM-X WSHP Controller is

conﬁ gured properly for your application. Refer to the VCM-X Controller

Technical Guide for more information. A handheld Modular Service Tool,

Modular System Manager, or System Manager Touch Screen connected

to the VCM-X WSHP Controller will allow you to conﬁ gure your ap-

plication. Refer to the VCM-X Operator’s Interfaces Technical Guide or

System Manager TS Technical Guide for more information.

The Compressors will stage in the following order:

Permutations 1, 2 & 3: Circuit A, 1

Compressor (A1) -> Circuit B, 1

Compressor (B1)

Permutations 4 & 5: Circuit A, 1

Compressor (A1) -> Circuit A, 2

Compressor -> (A2)

Circuit B, 1

Compressor (B1) -> Circuit B, 2

Compressor (B1) ->

Circuit A, 2

Compressor (A2) -> Circuit B, 2

Check all wiring leads at the terminal block for tightness. Be sure that

wire strands do not stick out and touch adjacent terminals. Conﬁ rm

that all sensors required for your system are mounted in the appropriate

location and wired into the correct terminals.

WARNING: Observe polarity! All boards must be wired

GND-to-GND and 24 VAC-to-VAC. Failure to

observe polarity could result in damage to the

boards.
