STATUS OUTPUTS
All the status outputs are logic outputs. Logic "0" means the
output is 0 V, logic "1" means the output is 5 V (Ro = 500
Ohm). This makes it possible to drive directly: an opto-
coupler, a TTL gate or a CMOS gate.
The Limit Status or
LIM-status
is "1" in case the DC output
voltage or current reaches the limit setting. Which limit circuit
is active can be seen on the front panel LED’s.
The Over Temperature Status or
OT-stat
us is "1" in case of
an over temperature, the OT LED will be on and the output
shuts down. As a pre-warning the OT LED starts to blink
when the unit runs hot but the situation of over temperature is
not reached yet. The status will still be low when the LED is
blinking.
The Current Control Status or
CC-status
output is "1" when
the unit is in CC-mode.
The Power Sink OverLoad Status or
PSOL-status
output is
"1" when the optional Power Sink is overloaded or
overheated.
The AC-Fail Status or
ACF-status
output is "1" in case of
Phase Loss or when the mains voltage is below 340 VAC.
The DC-Fail Status or
DCF-status
output is "1" when the DC
output voltage is either 5% below or above the set point.
When the unit is in CC-mode, DCF will always be "1", see
previous paragraph .

STATUS RELAY OUTPUTS
The power supply has 2 status relay outputs, with each a
change-over contact. They are connected to connector CON
D. The pins 1,2,3 are connected to the DCF-relay and pins
4,5,6 to the ACF-relay (see fig. 3 - 10).

After switching mains on, the unit will start with
the same settings for the voltage and the
current as it had before switching mains off
After switching mains on, the unit will always start up
with a voltage setting of 0 V and a current setting of 0
A. Once the unit is switched on, the voltage and current
can be set to the preferred value.
