1.2. GENERAL DESCRIPTION

The TSC 7320 controller utilizes a powerful ARM microprocessor, which provides high accuracy

for all voltage sensing and timing functions. The TSC 7320 is factory configured to control all the

operational functions and display features of the automatic transfer switch. All features of the

TSC 7320 are fully programmable from the front panel graphical screen display and are security

PIN protected.

2. INSTALLATION

CAUTION

This equipment contains static sensitive parts. Please observe the following

anti-static precautions at all times when handling this equipment. Failure to

observe these precautions may cause equipment failure and/or damage.

The following precautions must be observed:

 Discharge body static charge before handling the equipment (maintain exposed body contact

with a properly grounded surface while handling the equipment, a grounding wrist strap

can/should also be utilized)

 Do not touch any components on the printed circuit board with your hands or any other

conductive equipment

 Do not place the equipment on or near materials such as Styrofoam, plastic and vinyl. Place

the equipment on properly grounded surfaces and only use an anti-static bag for transporting

the equipment

2.1. GENERAL INFORMATION

NOTE

Installations should be done in

accordance with all applicable electrical

regulation codes as required.

The following installation guidelines are provided for general information only pertaining to

typical site installations. For specific site installation information, consult Thomson Power

Systems as required.

NOTE: Factory installations of Thomson Power Systems supplied transfer switches that have

been tested and proven, may deviate from these recommendations.

2.2. NOTES TO INSTALLER

If the transfer switch has programmable/multi-tap system voltage capability (refer to electrical

schematic), confirm the transfer switch has been configured for the system voltage.

WARNING

Failure to confirm and match transfer

switch voltage with the system voltage

could cause serious equipment damage.

If the transfer switch requires reconfiguring, the TSC 7320 controller will also require

reprogramming.

CAUTION

Qualified personnel must complete all installation and/or service work performed

only. Failure to do so may cause personal injury or death.

2.3. MOUNTING

When the TSC 7320 controller is supplied as part of a Thomson Power System automatic

transfer switch, the controller is mounted on the ATS door with screw clamps that are supplied

with the controller. When the TSC 7320 GHC is supplied loose for door mounting, it requires a

rectangular door cut-out that is 13.5” W x 7.75” L.

2.4. AC VOLTAGE SENSING INPUT

The TSC 7320 can accept direct AC voltage sensing inputs on the generator, utility and load

from 120-600VAC (nominal). Sources up to 600VAC (phase to phase) can be connected wye

or delta with grounded or ungrounded neutral without the need for additional sensing

transformers. The TSC 7320 voltage sensing can support the following types of electrical

systems:

Refer to SECTION 5.3 for system voltage programing instructions.

2.5. AC CURRENT SENSING INPUT

The TSC 7320 can accept 4 x 0 - 5Aac current inputs from the secondary windings of current

transformers (CT’s). CT’s are to be connected on the load side of the ATS (Phase A, B, C & N).

WARNING

Do not unplug any current transformer inputs while

energized as severe high voltages can develop which may

cause personal injury or death.
