SYMPTOM CHECK ACTION REF
No output. All displays and indicators
are blank.
Is the AC power cord defective? Check continuity, replace if
necessary. 3.7
Is the AC input voltage within
range? Check AC input voltage.
Connect to appropriate voltage
source. 0
3.7
Output is present momentarily but
shuts off quickly. The display
indicates “AC”. Does the AC source voltage sag
when load is applied? Check AC input voltage.
Connect to appropriate voltage
source. 0
Output is present momentarily but
shuts off quickly.The display indicates
“OUP”. Is the power supply configured to
Remote sense? Check if the positive or
negative load wire is loose. 3.10.8
3.11.3
Output voltage will not adjust. Front
panel CC LED is on. Is the unit in constant current
mode? Check current limit setting and
load current. 5.2.1
5.2.2
Output voltage will not adjust Front
panel CV Led is on. Check if output voltage is adjusted
above OVP setting or below UVL
setting. Set OVP or UVL so they will
not limit the output. 5.3
5.4
Output current will not adjust. Front
panel CV LED is on. Is the unit in constant voltage
mode? Check current limit and voltage
setting 5.2.1
5.2.2
Large ripple present in output. Is the power supply in remote
sense?
Is the voltage drop on the load
wire high? Check load and sense wires
connection for noise and
impedance effects. Minimize
the drop on the load wires. 3.9.2
3.9.5
3.10.3
No output. Display indicates “OUP” Over Voltage Protection circuit is
tripped. Turn Off the AC power switch.
Check load connections. If
analog programming is used,
check if the OVP is set lower
than the output. 5.3
No output. Front panel ALARM LED
is blinking. Display indicates “ENA” Check rear panel J1 ENABLE
connection. 5.8
Setup SW1 switch setting. 5.8
Display indicates “SO” Check rear panel J1 Output
Shut-Off connection. 5.7
Display indicates “OTP” Check if air intake or exhaust
are blocked. Check if the unit
is installed adjacent to heat
generating equipment. 1.2.7
3.5
5.13
Display indicates “Fb” Check Foldback setting and
load current. 5.5
Poor Load regulation. Front panel CV
LED is on. Are sensing wires connected
properly? Connect the sense wires
according to User’s Manual
instructions. 3.9
3.11.3
The front panel controls are
nonfunctional. Is the power supply in
Local-Lockout mode? Turn Off the AC power and
wait until the display turns off.
Turn On the AC power and
press front panel REM/LOC
button. 5.12
