5.1.3 Local Transmitter

Operation

The Model 344 has two local pushbuttons labeled FS (Fullscale)

and Z (Zero) located on the housing. These are used to set

range and damping when the controller block is configured

“OFF”. This is detailed in the following sections.

When the controller block is configured “ON” the ranging/

damping capabilities are not available. In this mode the

pushbuttons may be used to transfer between AUTO and

MANUAL control, change VALVE output, and change the

SETPOINT. This is detailed in the following sections.

Local Pushbutton Operation:

The “Pushbutton Mode” must be activated as described below to

use the Zero and Full Scale pushbuttons.

• The Pushbutton Mode is activated whenever either

pushbutton is pressed and held for a minimum of 5 seconds

and then released. The “PB” annunciator on the Digital

Meter will be lit while the Pushbutton Mode is active.

• The Pushbutton mode will automatically time-out after 1

minute.

• Failure to hold a pushbutton ON for a minimum of 5 seconds

will prevent entry into the Pushbutton mode.

• The pushbuttons are disabled when the transmitter is placed

in “CONFIGURATION HOLD,” as when downloading a

configuration.

Pushbuttons are enabled or disabled by jumper W1 on the

Electronics Module and are enabled by the factory. Jumpering

pins 2 and 3 equals ENABLE. When the jumper is in the

DISABLE position, the pushbuttons perform no function.
