Enable/Disable Control Via Rear Panel J1 Connector; Cv/Cc Signal; Ps_Ok Signal - TDK-Lambda Genesys GEN8-300 User Manual

When the unit is shut-off by J1 signal, the VOLTAGE display will show "SO" to indicate the unit state. J1
contact 15 is the SO signal input and contacts 2 and 3, IF_COM, are the signal return (connected
internally). Contacts 2,3 and 15 are optically isolated from the power supply output.
The SO control logic can be selected by the rear panel SW1 Setup switch. Refer to Table 5-2 for SW1

5.8 ENABLE/DISABLE CONTROL VIA REAR PANEL J1 CONNECTOR

Contacts 1 and 14 of J1 (Fig.4-2, Item 5) 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 5-3 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.
NOTE
Safe Start mode -If the Enable/Disable fault condition
clears when units in safe start mode recovery is by
pressing OUT button or by sending a 'OUT 1' serial
command.
Auto Restart mode - The output will return back ON
automatically when the Enable/Disable fault conditions
clears.

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 (Power supply is disabled)
*OVP *SO (Rear panel Shut-Off - Power supply is shut off))
*Foldback *IEEE failure (with optional IEEE interface)
*AC fail *Output Off

VORSICHT
Um das Gerät vor möglichen Schäden zu schützen,
verbinden Sie nie einen der Enable/Disable-Eingänge
mit dem Plus- oder Minus-Ausgangspotential.
Safe-Start-Modus - Im Safe-Start-Modus kehrt das
Netzteil erst dann in den Normalbetrieb zurück, wenn der
Enable/Disable-Eingang aktiviert wurde und zusätzlich die
OUT - Taste betätigt wird oder das Gerät ein "OUT1
"-Kommando über die serielle Schnittstelle empfängt.
Auto-Restart-Modus - In diesem Modus kehrt das
Netzteil automatisch in den Normalbetrieb zurück, sobald
der Enable/Disable-Eingang aktiviert wurde.
Verbinden Sie den CV/CC-Ausgang nur mit einer
Spannungsquelle bis maximal 30V DC. Verbinden Sie
den Anschluss stets über einen Vorwiderstand mit der
Spannungsquelle, oder begrenzen Sie den Strom auf
andere Weise auf max. 10 mA.
