5.8 ENABLE/DISABLE CONTROL VIA REAR PANEL J1 CONNECTOR

Contacts J1-1 and -14 (Figure 4-2, Item 5) serve as Output Enable/Disable terminals (by switch or relay). This
function is Enabled or Disabled by Dip-switch SW1-9. Refer to Table 5-3 for the Enable/Disable function and the
SW1 setting.

UP
To prevent possible damage to the unit, do not connect any of the Enable/Disable

Safe-Start mode: If the Enable/Disable fault condition clears when the unit is in Safe-Start
mode, recovery is made by pressing the OUT button or by sending an 'OUT 1' serial
command.
Auto-Restart mode: The output will turn back ON automatically when the Enable/Disable
fault condition clears.

5.9 CV/CC SIGNAL

The CV/CC signal indicates the operating mode of the power supply, Constant-Voltage or Constant-Current. The
CV/CC signal is an open collector output with a 30V parallel zener diode, at J1-13, referenced to the COM
potential at J1-12 (connected internally to the negative sense (-S) potential). When the power supply operates in
Constant-Voltage mode, the CV/CC output is open-circuit. When the power supply operates in Constant-Current
mode, the CV/CC signal output is low (0.0 - 0.6V) with a maximum sink current of 10mA.
Do not connect the CV/CC signal to a voltage source higher than 30VDC. Always
connect the CV/CC signal to voltage source with a series resistor to limit the sink

5.10 PS_OK SIGNAL

The PS_OK signal indicates a fault condition in the power supply. PS_OK is a TTL signal output at J1-16 and is
referenced to IF_COM at J1-2, -3 (Isolated Interface Common). When a fault condition occurs, the PS_OK level
is low, with a maximum sink current of 1mA. When no fault condition occurs, the PS_OK level is high with a
maximum source current of 2mA. The following faults will set the PS_OK to a fault state:


OVP
