7.Refer to step 2 above and select the new damping value. Count the number of steps (damping values) from “0” seconds to the selected value. This number “N” will be used in the following step 8.

8.Press and release the FULLSCALE pushbutton “N” times to step to the selected damping value.

9.Perform steps 3 and 4 above.

mode and PROCESS VARIABLE, SET POINT, and

 

VALVE values.

 

Open the sliding cover on top of the Transmitter's housing to

 

access the ZERO/FULLSCALE pushbuttons (Figure 1-1),

 

then refer to the following procedures to make any required

 

changes to the Controller's operation.

 

A. Change AUTO/MANUAL Control Mode

 

The active control mode is shown by a lit "A" (AUTO)

 

or "M" (MANUAL).

 

IMPORTANT

 

If the present control mode is AUTO, and

 

the Controller's A/M TRANSFER BLOCK

 

has been configured for "AUTOMATIC

 

MODE ONLY", a change from AUTO to

 

MANUAL cannot be made using the

 

pushbuttons.

 

1. Note the present control mode as indicated in the

 

Digital Meter. Simultaneously press and hold, for a

 

minimum of 5 seconds, the ZERO/FULLSCALE

 

pushbuttons, then release both buttons.

 

2. Confirm the transfer of mode control from "A" to

 

"M" or "M" to "A".
