3.6.1.
Supply alarms
HPS/T can work with network voltage variations of
15%, if these limits are exceeded HPS/T stops
and the led concerning the occurred alarm blinks, in this case HPS/T can be unblocked by means of
the button HARDWARE RESET or switching off and switching on the machine.
If the network voltage is too low HPS/T stops and the led
UNDERVOLTAGE
is lit.
If the network voltage is too high HPS/T stops and the led
OVERVOLTAGE
is lit.
3.6.2.
System alarms
In case of high temperature on the inside of HPS/T (more than 70°C) this one stop and the led
TMAX
is lit; In this case the HPS/T can be unblocked by means of the button HARDWARE RESET or
switching off and switching on the machine.
Also in case of bad operations of the overload sections (inverter) HPS/T stops and the led
INVERTER
is lit.
3.6.3.
Current alarm
HPS/T works a control on the output current that allows to support for an indefinite time the
output short circuit.
In case of loads that absorb a current superior than the nominal one, HPS/T works a limitation of
the same current.
This limitation is visualized by means of the led
LIMIT OUT
at the voice
CURRENT
.
In case of a limitation of current the output sinusoidal wave is no more guaranteed and so it will
show an harmonic distortion.
Not linear loads with an overload minor than the nominal one but with a very high crest factor
current make the current defence intervene.
Notice that if someone is working by limitation current, HPS/T keeps the effective value of the
output voltage equal to the set off value until the led concerning the voltage alarm switches on
(see at VOLTAGE ALARM).
This kind of alarm does not cause any block to HPS/T.
3.6.4.
Voltage alarm
HPS/T more than the output distortion control woks a control of the effective value of the output
voltage either in the configuration 2 wires or in the configuration 4 wires.
If the output voltage is not equal to the set off one a signal of error is visualized by means of the
led
MAX
V
at the voice VOLTAGE.
This kind of alarm does not cause any block to HPS/T.
