1.2. GENERAL DESCRIPTION
The TSC 800 controller utilizes microprocessor-based design technology, which provides high
accuracy for all voltage sensing and timing functions. The TSC 800 is factory configured to
control all the operational functions and display features of the automatic transfer switch. All
features of the TSC 800 are fully programmable from the front panel LCD display and are
security password protected. The LCD display screen prompts are in plain English, providing
a user-friendly operator interface with many display options available. The microprocessor
design provides many standard features, which were previously only available as add-on
optional features.
2. INSTALLATION
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 (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
Technology as required. NOTE: Factory installations of THOMSON TECHNOLOGY 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 800 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. AC VOLTAGE SENSING INPUT
The TSC 800 can accept direct AC voltage sensing inputs on the generator and utility supplies
from 120-600VAC (nominal). NOTE: Direct input voltage sensing can only be used when the
system utilizes a 3 phase, 4 wire distribution system which has the neutral conductor solidly
grounded. For 3 phase, 3 wire systems (i.e. no neutral) or high voltage systems, potential
transformers must be used (this is also the case where only 1 of the 2 supplies are 3 ph 3 w).
Refer to FIGURES 1-4 for voltage sensing connections.
2.4. AC CONTROL POWER INPUT
The TSC 800 is factory supplied for either 115VAC or 230VAC (nominal) control power input
voltage. Independent AC control power is required from both utility and generator supplies.
AC control power is utilized for internal TSC 800 control circuits and external control device
loads. The TSC 800 requires approximately 12VA AC power for internal control circuits. The

maximum external load is limited by output contact ratings (i.e. 10A resistive, 120/250VAC).
Total AC control power requirements for each supply must be determined by adding both
internal and external load requirements.
