to the selected
Power-Down
option (KILL/RAMP). If the
Kill
option is selected, the
channel will be switched off at the maximum rate available. If the
Ramp
option is
selected, the voltage will drop to zero at a rate determined by the value of the
Ramp
parameter programmed for that channel.
4.3.2
Under Voltage
The
Under Voltage
condition (UNV) occurs when at least one channel is in
Under
Voltage
condition, i.e. when:
•
the actual value of the channel output voltage is lower than the programmed
value.
The Under Voltage condition is signalled by the UNV output signal True and the relevant
red LED on.
4.3.3
Over Voltage
The
Over Voltage
condition occurs when at least one channel is in
Over Voltage
condition, i.e. when:
•
the actual value of the channel output voltage is higher than the programmed
value.
The Over Voltage condition is signalled by the OVV output signal True and the relevant
red LED on.
4.3.4
Trip
The
TRIP
condition occurs as at least one channel has tripped and has been switched
off due to an Over Current condition (see § 4.3.1, p.25).
This condition is signalled by the TRIP output signal which is asserted True and the
relevant red LED alight.
To recover from this state it is sufficient to turn the tripped channel On again or to
execute a clear alarm command via software.
4.3.5
Reset flag
RST FLAG
(RESET FLAG) output signal is TRUE (and relevant red LED on) after a
RESET occurred, according to the user’s settings. The type of reset which asserts RST
FLAG TRUE can actually be selected via the
Set-up
à
à
Reset Flag
menu (see
§ 7.1.22).
4.3.6
Check passed
CHK PASS
(CHECK PASSED)
output signal is True (and the relevant green LED on)
when the initial check of the system is successful and the system is ready.
