1.2.GENERAL INFORMATION

The following information is provided for general information only pertaining to TSC 80 transfer switch controllers. For information on the TSC 80e controller refer to product manual PM091.

NOTE:

Installations should be done in accordance with all applicable electrical regulation codes as required.

The following information is provided for general information only pertaining to TSC 80 transfer switch controllers installed in a Thomson Technology Automatic Transfer Switch as applied in a typical site installation. For specific site installation information, consult Thomson Technology as required.

CAUTION

contents subject to damage by

STATIC ELECTRICITY

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.

•Discharge body static charge before handling the equipment (contact a grounded surface and maintain contact while handling the equipment, a grounded 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 grounded surfaces and only use an anti-static bag for transporting the equipment.

1.3.SERVICE DISPLAY MODULE (SDM)

An optional hand held, plug-in Service Display Module (SDM) is available for the TSC 80 Transfer Controller. The SDM module provides an LCD screen to display additional detailed information on the operation and settings of the TSC 80 controller for simplified servicing/trouble shooting procedures. For detailed information, refer to the separate SDM module instruction manual (PM065).

1.4.NOTES TO TRANSFER SWITCH INSTALLER

1.4.1. SYSTEM VOLTAGE

If the transfer switch has programmable/multi-tap system voltage capability (refer to electrical schematic), confirm the transfer switch has been configured for the correct system voltage. If the transfer switch requires reconfiguring, the TSC 80 controller will require reconfiguration as well.

WARNING

Failure to confirm and match transfer switch voltage with the system voltage could cause serious equipment damage.

1.4.2. SYSTEM PHASING-HIGH LEG DELTA SYSTEMS

When the transfer switch is connected to 3 phase 4 wire delta systems, the “High” leg (Phase B, colored Orange), must be connected to Phase B of the Utility and/or Generator supply. This will ensure the ATS control power which is internally connected between phase A and neutral is maintained at 120VAC. Refer to figure below for further details.

WARNING

Failure to match correct system phasing

will result in serious damage to the

TSC 80 controller.

CAUTION!!!

All installation and/or service work performed must be done by qualified personnel only. Failure to do so may cause personal injury or death.

1.4.3. REMOTE START CONTACT FIELD WIRING

As a minimum, the remote engine start control field wiring shall conform to the local regulatory authority on electrical installations. Field wiring of a remote start contact from a transfer switch to a control panel should conform to the following guidelines to avoid possible controller malfunction and/or damage.

1.4.3.1.Minimum #14 AWG (2.5mm2) wire size shall be used for distances up to 100ft (30m)1). For distances exceeding 100 ft. (30m) consult Thomson Technology.

1.4.3.2.Remote start contact wires should be run in a separate conduit.

1.4.3.3.Avoid wiring near AC power cables to prevent pick-up of induced voltages.

1.4.3.4.An interposing relay may be required if field-wiring distance is excessively long (i.e. greater than 100 feet (30m)) and/or if a remote contact has a resistance of greater than 5.0 ohms.

1.4.3.5.The remote start contact must be voltage free (i.e. dry contact). The use of a “powered” contact will damage the transfer controller.

1.4.4. DIELECTRIC TESTING

Do not perform any high voltage dielectric testing on the transfer switch with the TSC

80controller connected into the circuit as serious damage will occur to the controller.

All AC control fuses and control circuit isolation plugs connected to the TSC 80 must

be removed if high voltage dielectric testing is performed on the transfer switch.

TSC 80 TRANSFER SWITCH CONTROLLER

2.DESCRIPTION

The TSC 80 controller utilizes microprocessor-based design technology, which provides high accuracy for all voltage sensing and timing functions. The TSC 80 is factory configured to control all the operational functions and display features of the automatic transfer switch.

The TSC 80 controller consists of two parts; a Lexan faceplate, which is mounted externally on the transfer switch door, and a printed circuit board (PCB), which is mounted inside the transfer switch on the enclosure door.

2.1.LEXAN FACEPLATES

The TSC 80 Controller Lexan faceplate is shown as in FIGURE 1. The Lexan pushbuttons and LED lights are connected to the main PCB via plug-in ribbon cable. The main features of the Lexan faceplate are described as follows with reference to FIGURE 1.

2.2.2. DIAGNOSTIC LED’S

The TSC 80 controller provides diagnostic LED lights, which are mounted on the printed circuit board as per FIGURE 2. Their functions are described as follows:

SYS OK	This LED flashes on and off at irregular intervals, which
	indicates the microprocessor is functioning normally.

TRANSFER TO UTILITY This LED is illuminated whenever the TSC 80 is initiating a signal to transfer to the Utility supply.

TRANSFER TO GEN	This LED is illuminated whenever the TSC 80 is initiating a
	signal to transfer to the Generator supply.
ENGINE STOP	This LED is illuminated whenever the TSC 80 is initiating an
	Engine STOP signal.
