9. FUNCTIONAL PROBLEMS
The lab mains unit does not work, the displays are not lit:
• Check the on/off switch (switch position "I" = on).
• Check that the mains cable is firmly connected to the lab mains unit and whether it is plugged into a proper mains
socket with protective contact (wall outlet).
• Check the functionality of the mains socket (e.g. fuse, circuit breaker, fault interrupter protection switch).
The connected consumers do not work:
• Check polarity at the DC output sockets (6, 12).
• Check that the current limitation is activated; if required, set a higher value for current limitation (or set the maxi-
mum value).
• Observe that the lab mains unit has three different voltage/current ranges that can be selected via the three but-
tons "16V/5A" (5), "27V/3A" (11) or "36V/2.2A" (10); see chapter 7. b).
When the consumer needs, for instance, an operating voltage of 30 V/DC, select the corresponding range with the
button "36V/2.2A". Only an output current up to 2.2 A is available here, however.
• Reduce the load of the lab mains unit.
• Check the technical data of the consumers (operating voltage, current consumption, voltage type).
