8.2.2 PID Configuration Parameters

HEATING PROPORTIONAL BAND ( 000.0 , 999.9 )%%

Full Scale ( - ) %.

If = 1000 °C, = 0 °C and = 50.0 then

Proportional Band = ( - ) * / 100.0

Proportional Band = (1000-0)*50.0/100.0 = 500 °C

HEATING INTEGRAL TIME (0000 sec, 3600 secs)

It can be changed by the user. When Tune operation stops, it can be

changed by the device. If it is 0, integral control part does not run. When

tune operation stops if this parameter is 0, this parameter can not be

changed because of integral control part does not run.

HEATING DERIVATIVE TIME (000.0 sec, 999.9 secs)

It can be changed by the user. When Tune operation stops, it can be

changed by the device. If it is 0, derivative control part does not run.

When tune operation stops if this parameter is 0, this parameter can

not be changed because of derivative control part does not run.

Relay Output :

SSR Output :

Output period must be short for stable process control. Relay must

not be used in short output periods because of limited life of their relay contact

(number of open/close events). Relay output must be used as control output in

values near to 30 seconds or greater than this value.

If short output period is needed in a system (approximately 1-2

seconds) SSR driver output module as last control element is recommended.

CONTROL PERIOD FOR HEATING OUTPUT (1 sec, 150 secs)

It is control period for heating. While motorized valve control runs, if

is heat or cool, this parameter is not visible.

If any output is configured as heating PID ;

,,,,,, ,, ,,

, , , parameters are visible.

If any output is configured as cooling PID ;

,,,,,, ,, ,,

,,,, parameters are visible.

If no output is configured as PID ;

Only , parameters are visible in PID CONF menu.
