b) Pressure Switch Verification

Pressure switches are devices that receive a pressure signal and have relay

alarm. The relay is activated whenever the pressure passes above or below a certain
setpoint alarm.

Connect the pressure switch relay output to the switch input of PCON-Y17,

RTD1

and

RTD4

terminals, and make the pneumatic connections as illustrated in the figure

below.

Fig. 47

- Pressure Switch Verification

Select

SWITCH

in the

Input (Auxiliary)

menu and configure the Pressure Control

parameters (the

Control

Operation Mode must be selected).

To perform the automatic pressure test, press the PRESSURE SWITCH as

shown in the following figure.
