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.

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.
