5. On/Off control (rear panel) --- By voltage: 0.6V = Disable, 2-15V = enable (default) or dry contact, user selectable logic
6. Output current monitor ---
0 5V or 0 10V, accuracy 1%, user selectable
7. Output voltage monitor ---
0 5V or 0 10V, accuracy 1%, user selectable
8. Power supply OK signal --- Yes. TTL high-OK, 0V (500ohm impedance)-Fail
9. Parallel operation --- Up to Four (4) identical units may be connected in Master/Slave Mode with ‘Single’ wire connection.
In Advance parallel feature, the current of Master Unit, multiplied by number of units connected in parallel, is
made available on digital interface and displayed on front panel of Master unit. Remote analog current
monitor of the Master is scaled to output current of the Master unit (only).
10. Series operation --- Possible (with external diodes), up to identical 2 units with total output not to exceed +/-600V from chassis
ground.
11. CV/CC signal ---
CV: TTL high (4 5V) source: 10mA, CC: TTL low (0 4V): 10mA
12. Enable/Disable --- Dry contact. Open: off, Short on. Max. voltage at Enable/Disable Contacts 6V
13. Remote/Local selection ---
Selects Remote or Local operation by elect. Voltage: 0 0.6V/2 15V, <0.6V = Local 2-15V = Remote.
14. Remote/Local signal --- Signal operating mode in use.
