Chapter 4 Operating Instructions
Use and Function
of Controls
The Series 8630 and 8630B loads have no operating controls, other
than the ON/OFF switch; therefore, they do not require an operator
in attendance. The 8630 series is equipped with two indicators. One is
a pilot light in the ON/OFF switch, to warn that the ac power is being
applied. The other is the coolant level gauge, referred to in Chapter 3
- Installation. The 8630B series is equipped with one indicator which
is the coolant level gauge, referred to in Chapter 3 - Installation.
Initial Adjustments
and Control
Settings
There are no adjustments or settings required beyond confirming that
the cooling system contains an adequate level of coolant for proper
operation. Refer to Chapter 3 - Installation.
Equipment Startup
1. Make sure coolant level is adequate, and verify fan operation.
2. Turn interlock supply on.
3. Turn on 115 V or 230 Vac power.
CAUTION
Do not operate the load without proper coolant levels. Operation without
sufficient coolant can damage the unit.
WARNING
Never attempt to connect or disconnect an RF cable while power is
on at the RF power source. Radiated RF energy is a potential health
hazard.
CAUTION
Do not apply more than the rated RF power to the load. Excessive
RF power will damage the load resistor.
CAUTION
Do not block air flow. Air enters the housing through the circular
fan openings and exhausts through the grille opposite.
CAUTION
Do not operate the load without connecting the interlock. Even
momentary application of power to the load while the cooling
circulation is off, or possibly functioning improperly, will cause
almost immediate destruction of the resistor element.
