Section IV. Detailed Operation
4.1 Normal or Standby Operation
a. Normal : In this mode the standby feature is
defeated and temperature control is in accordance
with the IMP controller(s) settings.
b. Standby : With the toggle switch in this position,
the standby mode is engaged. This will set the tem-
perature of all IMP controllers operating in automatic
mode to a standby temperature of 200 deg F(93 deg C).
(1) Any IMP controller operating in manual mode will
have its output power level reduced to 1/4 of its
present level.
(2) When SAM and IMP controller(s) are in use at nor-
mal operating temperature [setpoint above 230 deg
F (119 deg C)], switching to standby mode will result
in an over temperature alarm until all zones cool
down to below 230 deg F (110 deg C).
