System Installation
GMW-25 2-5
Pin Name Type Description
4 RF ON/OFF
Control (+)
DI A voltage between this and Pin 17 will turn
RF power ON.
Leaving it open or applying zero voltage will
turn RF power OFF.
The nominal voltage to turn RF ON is
selectable b5 V or +24 V via a
jumper on the control board, however it
should not exceed 30 VDC.
5 Power set point (+) AI A linear DC voltage to set the output power
level.
0 V = 0 W and the max. value is adjustable
between 0 and 12 VDC. Input impedance is
100 k ohms balanced differential to ground.
6 +28 VDC User voltage for interface purposes. Rated
50 mA max.
7 RF ON (E) DO Emitter side of isolated transistor switch.
(See Note 1)
Transistor ON - RF ON.
Transistor OFF - RF OFF.
8 Analog remote
enable
DI Ground referenced logic input. (See Note 2)
LOW - Selects analog remote control mode.
HIGH - Disables analog remote control
mode.
Leaving this pin disconnected will ensure a
configurable HIGH or LOW state (Rev. A
Interface only).
Note: If the generator is in digital remote
mode, it cannot switch to analog remote
mode until the digital remote mode is
disabled. Therefore, setting this pin low will
have no effect until the digital remote mode
is disabled.
9 Overheat (E) DO Emitter side of isolated transistor switch.
(See Note 1)
Transistor ON - Overheat fault.
Transistor OFF - No fault.
10 Interlock This pin should connect to Pin 23 to
complete the interlock chain.
If the interlock chain is broken, the AC
contactor will open. External circuit should
be capable of switching 100 mA at 24 VAC.
