-
«Umax» - the voltage is not enough to achieve the specified current for this load (the
load resistance is too high or the contact between output clamps with the load is
broken)
-
«Р lim»
- not enough power to achieve the specified current for this load.
The potentially «dangerous» unlimited mode of generation is depicted with a special
«alert» indicator « ». The «default» increase of the output voltage is limited by level safe
for a human (24V). If necessary (for tracing the cables) it is possible to operatively remove
the limitation (temporarily) if the appropriate precautions are taken.
Here the decision should be made about necessity to correct the parameters of output
current. For this purpose the test tracing is recommended.
3.8 Start and stop of generation
If after power is turned on the button « » pos.10 is depressed
shortly
in the standby mode
(«stop»), the generation and automatic matching
–
step-by-step increase of voltage at the
output until the specified current is reached shall be started. It is recommended to monitor
the power life indicator (« » on the field «POWER»). If the output voltage («V») exceeds
«24.0» the automatic matching shall stop anyway. If the specified current is not reached, the
indicator “Umax” shall be on in the field «MATCHING». This is a
safe mode
set by default
when the power is on.
If higher output voltage is required to achieve the necessary current during tracing of the
cables (AND APPROPRIATE SAFETY MEASURES ARE TAKEN!), the automatic matching can be
started in the «unlimited» mode. For this purpose, press the button « » in the standby
mode (“stop”) and keep it depressed until the “alerting” indicator «
» is on. That means
the potentially dangerous “unlimited” mode is activated, the output voltage may exceed 200
V with internal power supply and 300 V with added 12V external power supply. The
«unlimited» mode shall exist until the power is off.
