7.6 Troubleshooting, fault diagnosis and repair
7.6.1 No output voltage present
 Mains voltage present at X1 and within tolerance?
Upstream fuses checked?
For devices in the DC series: correct polarity?
 For parallel operation: Are any decoupling diodes in output X2
correctly polarized?
 Are jumper X11:7 and X11:8 present or is the contact for External
On/Off closed? Is switch S3 (On/Off) switched on?
 Output X2 polarity reversed?
 Has the monitoring U
Out
≥ responded (LED H6 U
Out
> lights up)?
 Press reset S8 (section 6.2.8) and check the overvoltage
monitoring setting with potentiometer R10 U
Out
≥ (section
6.2.5). Make sure which setpoint value U
Out
is selected (section
6.3.4).
 Has the overtemperature monitor responded (LED H5 Temp. >
illuminated)?
 Press reset S8 (section 6.2.8)!
7.6.2 Deviation of the output voltage
 Is the device operating in the current limit due to overload?
Reduce the load!
 Is the wrong internal setpoint U
Out
selected?
 Is the setting of the selected potentiometer U
Out
(R14-R17)
incorrect?
Adjust the output voltage (section 6.2.5)!
 Are the bridges X12:1-2 and X12:3-4 available?
Build bridges!
 If an external sensor line is used, is the sensor line open?
 If external setpoint specification, setpoint correct?
