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: This is the default operating mode, providing full access to all programming
and readback functions via front panel displays, controls, and indicators (see PAR. 3.2).
• 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 [-1200 Models] or a LAN port [-1.2K models]. The
digital ports are described in the KLP Developer’s Guide. The power supply automati-
cally goes into digital remote mode when commands are accepted via one of the digital
ports.
• Analog Remote Mode: This mode is selected via a jumper wire at the analog program-
ming port prior to initial turn-on, and provides limited access to programming and read-
back functions (see PAR. 3.4).
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. Sta-
tus 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
MODL
for 2 seconds while DC VOLTS and DC AMPERES dis-
plays show the maximum voltage and current capability of the unit.
• 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.
3.2.6 to define a virtual model.
• Status display flashes
PROT
for 2 seconds while DC VOLTS and DC AMPERES dis-
plays show previously stored OVP and OCP trigger levels. NOTE: to reprogram OVP
or OVC, refer to PAR. 3.2.8.
NOTE: To eliminate the display of model, virtual model, and protection levels on power-up,
refer to PAR. 3.2.13.4 for quick boot.
