the user’s responsibility to NOT attempt multiple consecutive restarts without eliminating
the fault condition.
• AUTOmatic - When a fault configured for AUTO recovery is detected, the output is dis-
abled as long as the fault condition exists. Once the fault condition is no longer present
(e.g., the unit has cooled down after an overtemperature fault) the output is enabled at
the last actual settings for voltage and current, as opposed to setpoints (see PAR.
3.2.9.3 for Last Setting Recall). To alert the user to this risk, if any fault is set to AUTO
recovery, the status display briefly shows
AUTO
after a) any fault recovery, b) any output
enable action or c) upon leaving Setpoint mode. In addition, if AUTO recovery is
selected for source power failure (PWR) faults, the status display flashes
AUTO
for one
second as part of the power-up sequence.
WARNING
When AUTOmatic recovery is selected, upon removal of the fault condi-
tion the output recovers to enabled (ON) state regardless of the output
state (ON of OFF) at the time of the occurrence of the fault. For this rea-
son, AUTOmatic recovery mode is best suited to applications where it
is anticipated that the output is always enabled. For safety reasons,
when servicing circuits powered by the output always switch the KLP
front panel circuit breaker OFF.
If more than one fault occurs, the fault with the lowest risk level determines the unit’s response,
however multiple faults will cause the output to be off upon recovery, even if set to AUTO.
The factory default configuration is PROTECT for all faults. Note that some faults have limited
options. The recovery options for each fault are:
• OVP (Overvoltage Protection fault) PROTECT or SAFE
• OCP (Overcurrent Protection fault) PROTECT or SAFE
• OLF (Output Lead Fault) PROTECT or SAFE
• TEMP (Temperature fault) PROTECT, SAFE or AUTO
• PWR (Loss of source power fault) PROTECT, SAFE or AUTO
• FAN (Fan failure fault) PROTECT (not configurable)
NOTE: When using a master/slave configuration, all faults are set to PROTECT and power to
both units must be cycled to clear a fault.
1. Enter
UTIL
menu (see PAR. 3.2.16, steps 1 through 3) and rotate either VOLTAGE or CUR-
RENT control until status display reads
SYST
, then tap DC OUTPUT switch. Rotate either
VOLTAGE or CURRENT control to until the status display reads
RCOV
.
The DC VOLTS and DC AMPERES displays show a series of bars that give a snapshot pic-
ture of the recovery configuration as defined in Figure 3-2. The location of the bar (top, mid-
dle, or bottom) corresponds to the risk level (high for AUTO, middle for SAFE, and low for
PROTECT). The character positions are assigned to the configurable faults as shown.
