B) TSC 80 POT Setting =
(Desired Drop-out voltage x 100)
TSC 80 Voltage Jumper Setting
Example:
for 440V system, 85% of 440V= .85 x 400V= 374V
TSC 80 POT Setting = (374 x 100)
480
TSC 80 POT Setting =
78%
NOTE
The TSC 80 voltage jumper setting must be set to be equal to the
nominal system voltage level or the next highest setting available (e.g.
440V system voltage must use 480V jumper setting).
4.1.2. SYSTEM FREQUENCY
One jumper is provided to set the required system operating frequency of the
TSC 80 controller.
•
For 60Hz applications, no configuration jumper is required.
•
For 50Hz applications, a jumper must be placed across the 2 pins,
adjacent to the text on the PCB.
When a system frequency is selected, the TSC 80’s generator frequency
setpoint percentage setting will be automatically programmed to correspond to
the sensing input frequency (e.g. with a 60Hz system frequency, and a 90%
under frequency potentiometer setting, the under frequency sensor will be
activated below 54.0 Hz).
NOTE
When a configuration jumper is not required, the jumper should
be connected to only one pin of the header to conveniently
store it for future use.
4.1.3. SYSTEM PHASES
One jumper is provided to set the required number of system phases for the
TSC 80 controller.
•
For 3 phase applications, no configuration jumper is required.
•
For single-phase applications, a jumper must be placed across the 2
pins, adjacent to the text on the PCB. Phase C voltage sensing input is
ignored in the single-phase mode.
