TS 910 TRANSFER SWITCH
PM140 REV 2 14/01/23 46 Thomson Power Systems
• 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 PHASE 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: 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.
18.15.4 GEN EXERCISE LOAD TEST MODE (LOAD) JUMPERS
Two jumpers are provided to set the required exercise testing mode for the TSC
9 controller as follows;
• ON: for applications where the generator is to be exercised with load, a
jumper must be placed across the 2 pins, adjacent to the text on the PCB
‘ON’:
• OFF: for applications where the generator is to be exercised without load
(i.e. Off load), a jumper must be placed across the 2 pins, adjacent to the
text on the PCB ‘OFF’:
Only one jumper must be placed on the selection jumpers. Failure to do so
will cause improper operation.
NOTE
The OFF load Test mode is the factory default setting.
