Procedure for Manual Control Pre-Set

1- Adjust controller for closed-loop operation and obtain

good molded parts. This will adjust the controller to the

proper temperature.

2- Position the module select switch to open-loop and set

the manual control knob to roughly 25%. Wait for 10

seconds, than momentarily switch to closed-loop mode

to examine the temperature. If it is above the setpoint,

the manual power is too high to maintain proper

temperature. If it is below setpoint, the manual power

is too low. Adjust the power control knob accordingly,

wait for 10 seconds, then re-examine the temperature

by switching momentarily to closed-loop mode. Repeat

this procedure until the temperature is the same in

either automatic or manual control.

E.Standby Heat (SAM module only)

Standby heat is a low heat level used to keep heaters and

associated equipment warm. Its purpose is to prevent moisture

build-up in heaters and equipment during idle periods and to

provide fast start-up when returning to normal operations.

When using a Standby Alarm Module (SAM), activate the standby

switch. The SAM will send a standby command to all controllers.

A controller, upon receiving the command, will respond accord-

ingly to its present mode of operation:

a- If the controller is in closed-loop mode, the set-

point becomes 200 degrees F (93°C) regardless of

the setpoint switch setting. The Remote Standby

Indicator (the decimal of the last digit) will be

1 2 ... 5 6 7 8 9 10 11 12 13 14 15 ... 22 23
