5.8. Enable/Disable Control via Rear Panel J1 Connector
Contacts 1 and 14 of J1 (Fig.4-4) serve as Output Enable/Disable terminals by switch or
relay. This function is enabled or disabled by the SW1 Setup switch position 9. Refer to
Table 5-2 for Enable/Disable function and SW1 setting.

CAUTION
To prevent possible damage to the unit, do not connect any of the
Enable/Disable inputs to the positive or negative output potential.
If the Enable/Disable inputs are opened when the unit is in Safe Start mode,
it is required to short the Enable/Disable inputs and then press OUT button or
send OUT1 command to resume operation
5.9. CV/CC Signal
CV/CC signal indicates the operating mode of the power supply, Constant Voltage or
Constant Current. CV/CC signal is an open collector output with a 30V parallel zener, at J1-
13, referenced to the COM potential at J1-12 (connected internally to the negative sense
potential). When the power supply operates in Constant Voltage mode, CV/CC output is
open. When the power supply operates in Constant Current mode, CV/CC signal output is
low (0-0.6), with maximum 10mA sink current.
CAUTION
Do not connect CV/CC signal to a voltage source higher than 30VDC, always
connect CV/CC signal to the voltage source with a series resistor to limit the sink
current to less than 10mA.
5.10. PS_OK Signal
PS_OK signal indicates fault condition in the power supply. PS_OK is a TTL signal output at
J1-16, referenced to IF_COM at J1-2, 3 (Isolated Interface Common). When a fault condition
occurs, PS_OK level is low, with maximum sink current of 1mA; when no fault condition
occurs, PS_OK level is high with maximum source current of 2mA. The following faults will
set the PS_OK to Fault state:
*OTP*Enable/Disable open
*OVP *SO (Rear panel Shut-Off)
*Foldback *IEEE failure (With optional IEEE interface)
*AC fail *Output Off
