c. Fan failure (FAN). Monitors all three internal cooling fans; trips if failure of any fan.
d. Output Lead Fault (OLF). Monitors output power and sense leads; trips if any discontinuity
(open circuit) is detected in load connections.
e. Source Power Loss (PWR). Monitors internal d-c bus voltage at output of PFC; trips if low
a-c input or PFC failure occurs.
1.5.10 INTERNAL RELAY
An internal relay provides common, normally open and normally closed contacts available to the
user via the analog I/O connector. This relay is normally programmed (factory default) to ener-
gize upon detection of a system fault (FLT mode); see PAR. 1.5.9 for a list of faults. The relay
may also be programmed to be energized at the user’s discretion from the front panel (MAN
mode), or as part of a user-specified program using LIST commands (LIST mode). Refer to
PAR. 3.2.17.1 for details.)
1.5.11 MASTER/SLAVE CONTROL [STANDARD MODELS ONLY]
For applications that require the use of multiple standard KLR power supplies in either series
(for higher voltage) or parallel (for redundancy or higher current) the master/slave feature allows
a single power supply (the master) to automatically control both outputs to achieve the desired
output. Refer to PAR. 2.7.8 and 3.2.14 for details.
