15 INTERLOCK-RTN Ground return for External Interlock (pin 2)

16 GNDI Ground return for pins 3,4,5,6,7,19. Internally connected to

chassis ground.

Connect to system controller common or ground reference

17 GNDI Ground return for pins 3,4,5,6,7,19. Internally connected to

chassis ground.

Connect to system controller common or ground reference

18 RFENABLED RET Ground return for pin 8 (RFENABLED* signal).

For units manufactured on or before July 30, 2005, this pin is

internally connected to chassis ground (GNDI).

For unit manufactured on August 1, 2005 and later, this pin may

be configured as internally connected to chassis ground (GNDI)

(factory default configuration) or isolated from chassis ground

(OEM custom configurations). Configuration is set at the

factory.

Connect to system controller common or ground reference.

19 RL-IN Remote Limit input. Analog input, 0 to +5VDC range. Use pin

16 or 17 (GNDI) for return reference.

Used in dual-bias or multiple power supply systems to fold-back

the power supply’s output power if reflected power is detected

by another power supply in the system. Output power folds

back in response to an external voltage applied to this input.

Foldback threshold is factory preset at +5.00VDC (Disabled).

Consult factory for assistance.

20 RL-OUT Remote Limit Output. Analog output, 0 to +10VDC range.

Buffered, high-speed, non-linearized directional coupler

reflected power signal. Return reference is pin 23.

Used on dual-bias or multiple power supply systems. Consult

factory for assistance.

21 PHASE External Phase Sensor Input. Analog Input, -10.0VDC to

+10.0VDC range.

Used in conjunction with the Variable Frequency Tuning (VFT)

feature. On VFT-enabled units with VFT Feedback Mode set to

“PHASE TUNE MODE +” or “PHASE TUNE MODE –“ the

volta

e si

nal from an external

hase detector is used to steer
