A Supply Voltage Terminals
Screw terminals, two negative pins.
+
Positive supply voltage terminal
–
Negative (return) supply voltage terminal
B Chassis Ground Terminal
To be connected on the top side of the housing with a ring-type
terminal (ring cable lug) which is suitable for a M4 screw.
Connection of the chassis to ground (earth) is optional and only
required for a view specific applications.
C Signal
Connector
4-pole plug connector with screw termination comprises the
following signals:
- “Active” signal, for details see chapter 9.
- “Ready” signal, for details see chapter 10
- “Inhibit” input, for details see chapter 11
D Status
LED
This green LED indicates that the following information:
- OFF: Capacitors are discharged or supply voltage is
below
22V.
- ON: Capacitors are fully charged
- Slow flashing (1.25Hz):
Capacitors are getting charged.
- Fast flashing (10Hz):
Capacitors are getting discharged.
E Back-up Threshold Jumper
Option 1: Fixed mode (Jumper in position 2-3)
The unit switches to buffer mode as soon as the voltage falls below
22.5V.
Option 2: Variable mode (Jumper in position 1-2)
Unit switches to buffer mode when input voltage decreases by 1V.
Voltage changes slower than 0.54V/s will be ignored if the voltage is
above 22.5V. Below 22.5V buffering starts immediately.
For more details see chapter 5.
