TS 910 TRANSFER SWITCH

Thomson Technology
The following configuration jumpers are provided on the printed circuit
board to program the TSC 9 controller:
WARNING
The configuration jumper settings must not be changed while the
Transfer Switch and TSC 9 controller are energized. All sources of
power to the transfer switch must be de-energized prior to changing any
configuration jumper settings. Failure to do so may cause personnel
injury and/or death.
18.15.2.
SYSTEM VOLTAGE JUMPERS
Two jumpers are provided to set the required system operating voltage (i.e.
Phase-to-Phase Voltage) of the TSC 9 controller and transfer switch as follows;
•
208V
: For 208V nominal applications, a jumper must be placed across
the 2 pins, adjacent to the text on the PCB ‘208V’.
•
240V
: For 240V nominal applications, a jumper must be placed across
the 2 pins, adjacent to the text on the PCB ‘240V’.
Only one jumper must be placed on the voltage selection jumpers. Failure to do
so will cause improper operation. When a system voltage is selected, the TSC
9’s utility and generator under voltage set point percentage setting will be
automatically programmed to correspond to the sensing input voltage (e.g. with
a 240V system voltage selected, and a 70% under voltage setting, the under
voltage sensor will be activated below 168VAC).
18.15.3.
SYSTEM PHASES JUMPERS
Two jumpers are provided to set the required number of system phases for the
TSC 9 controller as follows;
•
1 PH
: For single-phase applications, a jumper must be placed across
the 2 pins, adjacent to the text on the PCB ‘1 PH’. Phase C voltage
sensing input is ignored in the single-phase mode.
•
3 PH
: (FUTURE USE) For three-phase applications, a jumper must be
placed across the 2 pins, adjacent to the text on the PCB ‘3 PH’.
Only one jumper must be placed on the selection jumpers. Failure to do so
will cause improper operation.
