Interlock Indicators:
 Ref. Pwr: this is a warning of a high reflected power level and illuminates if the
reflected power exceeds 16% of the maximum capable generator output.
 Cooling: this relates to over temperature of the internal power amplifier
module. If illuminated, RF On will not function until module has reached a safe
temperature.
NB. This interlock will operate when there is :
 Inadequate ventilation
 Defective cooling.
 RF module fault.
 In the event that RF operation is interrupted the interlock state will latch until
cleared by pressing RF off or removing the “Remote RF on” signal.
 Ext. interlock: this is operated by connecting the 25 way d connector (remote) on
the rear panel pin 13 to +12V pin 25.
 NB. when ext. Interlock (or any other interlock) is not made, the RF Off light will
not illuminate.
 Remote: this operates when either remote output set or remote RF On/Off
request are enabled.
