SECTION 3 - OPERATION
3.1 GENERAL
This section explains how to operate the KLP Power Supply. Series KLP feature three modes of
operation:
• Local Mode (see PAR. 3.2): This is the default operating mode, providing full access to
all programming and readback functions via front panel displays, controls, and indica-
tors.
• Digital Remote Mode (see PAR. 3.3): This mode is selected via commands transmitted
through one of the two digital ports. One port is configured for IEEE-488 (GPIB), The
second port is either an RS 232 port [standard models] or a LAN port [E-Series models].
The digital ports are described in the KLP Developer’s Guide. The power supply auto-
matically goes into digital remote mode when commands are accepted via one of the
digital ports.
• Analog Remote Mode (see PAR. 3.4): This mode is selected via a jumper wire at the
analog programming port prior to initial turn-on, and provides limited access to program-
ming and readback functions.
3.2 LOCAL MODE OPERATION
Local operation of the KLP Power Supply is accomplished via the front panel switches and con-
trols illustrated in Figure 2-1 and described in detail in Table 2-1. Separate 4-digit LEDs display
actual output voltage and current; these same displays show set points and limits as well. Status
and fault indications are provided by a 4-character alpha-numeric display.
3.2.1 TURNING THE POWER SUPPLY ON
1. To turn the power supply on, set POWER ON/OFF circuit breaker (1, Figure 2-1) to ON.
Apply firm, continuous pressure to rocker actuator until fully engaged (right side of rocker
actuator locked parallel to front panel). If actuator does not lock when released, allow actua-
tor to return to starting position, then wait a few seconds before repeating turn-on sequence.
DO NOT attempt to “tease” the switch contacts closed by repetitive press-and-release
action. The circuit breaker is “trip-free” design; if overload exists, contacts cannot be held
closed by actuator.
2. When the power supply is turned on, it performs a self-test and displays the following infor-
mation:
• Status display flashes
KLP
for 2 seconds while DC VOLTS and DC AMPERES dis-
plays show the maximum voltage and current capability of the unit.
• Status display flashes
LXI
for 2 seconds if unit is an E-Series model
• Status display flashes
RODC
for 2 seconds if unit has the Rapid Output Discharge Cir-
cuit option installed.
• Status display flashes
VIRT
for 2 seconds while DC VOLTS and DC AMPERES dis-
plays show the maximum voltage and current allowed for a previously programmed vir-
tual model. To reprogram the maximum allowable voltage and/or current, refer to PAR.
