The table below lists the various controls and indicator associated with this equipment.
Figure 3.1 on the following page illustrates the location of the items listed in the table.
TABLE 3- 1. CONTROLS AND INDICATORS
1 CIRCUIT BREAKER Controls application of line power to equipment . ( on main cabinet)
2 VOLTS control Multi-turn control used to set the output voltage.
3 FREQ control Multi-turn control used to set the output frequency.
4 OUTPUT switch Controls internal power relay to allow on/ off switching of the load
connected to the output terminals
.
5 RANGE switch Provided on TD option units only. Used to select output voltage range.
6 PHASE adjust trim Allows adjustment of electrical phase difference between outputs.
Factory set to 120 electrical degrees. Approximate range +/- 45 degrees
.
See operating instructions.
7 LINE DROP COMP
adjust
Provides compensation for resistive losses (I/R) in output wiring . One
trimmer for each phase. See operating instructions.

DIGITAL READOUTS A 3 digit LED readout is provided for : Voltage, Current, & Frequency.
The voltage and current displays indicate the True RMS value.
9 METER SELECTOR A 3 position rotary switch selects which phase is currently displayed
on the front panel digital displays.
10a C. CURRENT indicator Illuminates to indicate the power supply is operating in the constant
current protection mode. The output voltage is reduced to limit the
current and maintain a sine wave current into an overload.
10b OVER-TEMP indicator Illuminates to indicate the power source is disabled due to excessive
internal temperature. The power source will recover once the
temperature falls below a safe limit.
10c OVERLOAD LATCH
indicator
Illuminates to indicate the power supply is disabled due to excessive
output current or short circuit. The power supply must be turned off for at
least 30 Seconds to clear this type of fault.
11 AC OUTPUT
Provides load connections. 1/4" inside diameter ring lugs recommended.
USE LOWER SCREWS ONLY!
12 REMOTE PRGM
9 pin “D” connector provided for remote analog control inputs .
See operating instruction in section 3.4
13 GND stud Heavy stud for earth connection .
14 DC INPUT
Used to c/- 250VDC from lower input chassis to control chassis.
Standard units are factory wired.
15 Control Terminals
or
Optional temp sense
Optional Terminal connection. Used for thermal switch on CE type units.
Used for fan and output relay control on T15 units. The temp switch
monitors the input power supply temperature and will shut down the
output relay if overheating should occur.
