PARAMETER ENTRY

The PAR button is used to select the desired parameter. To modify the

parameter setting, use the UP and DOWN buttons. Press PAR to enter the new

value. The controller progresses to the next parameter. In a Configuration

Parameter Module, pressing the DSP button causes the new value to be

rejected, the controller displays “End”, and returns to the Normal Display

Mode. For those parameters outside the Configuration Parameter Modules, the

new value takes effect and is committed into controller memory WHILE the

value is keyed in. The following is a list of commonly modified parameters:

Setpoint

Output Power

Output Power Offset

Proportional Band

Integral Time

Derivative Time

Proportional Band #2

Integral Time #2

Derivative Time #2

Directed Setpoint (Cascade)

Ratio

Bias

Alarm 1 Value

Alarm 2 Value

Note: While in a Configuration Parameter Module, all new parameters are

rejected and the old ones recalled if power is removed from the controller. If

power is removed while modifying any parameter, be certain to check the

parameter for the proper value.

NORMAL DISPLAY MODE

In the normal display mode, the process value is always displayed in the

main display. By successively pressing the DSP button, one of these

operational parameters can be viewed in the secondary display (model

dependent):

Setpoint

% Output Power

Second Analog Input (Remote Setpoint)

Process Setpoint Deviation

Each of these displays can be independently locked out from appearing or

from being modified by the user (see

Lockouts Module, page 27). Only from

the normal display mode can access be gained to the other modes

(Unprotected, Protected, or Hidden).

MODIFYING A SECONDARY DISPLAY PARAMETER FROM

THE FRONT PANEL

The controller must be in the normal display mode to modify the secondary

display parameters. The Setpoint value and % output power (in manual mode)

are the two parameters which may be modified. The other parameters are

read-out values only.

Setpoint Value - Use the up and down arrow buttons to modify the setpoint

value when viewed, if not locked. If locked, the setpoint can be changed in

the unprotected mode when “SP” is viewed, independent of viewing in the

secondary display. The setpoint value is confined to the programmable

setpoint limit values (SPLO & SPHI, Input Module 1).

% Output Power - The % Output Power can only be changed when the unit is

in the manual mode. See

Manual (User) and Automatic Operations, page

12. The annunciator % PW lights, and the Manual annunciator flashes

when viewed. Use the up and down arrow buttons to modify the % Output

Power if not locked. If locked, the % output power can be changed in the

unprotected mode when “OP” is viewed, independent of viewing in the

secondary display. The % output power is not confined to the programmable

output power limit values (OPLO & OPHI, Output Module 2).
