FAULT STATUS relay is usually used in conjunction with an analog

output to obtain validity information for the output value.

NOTE

If a barometer loses its power, all status-based relays are released

similarly to the case of an instrument failure.

Enabling/Disabling Relays

You can deactivate the relay outputs for example for service purposes

of your system.

Setting Relay Outputs

RSEL

Use the serial line to select the quantity, setpoints, and hysteresis or

enable/disable the relay outputs. The factory setting is that all the

relays are disabled. Enter the

RSEL command.

RSEL [q1 q2...]

where:

q1 = quantity for the relay 1 or Fault

q2 = quantity for the relay 2 or Fault

and so on

Use the quantity abbreviations presented in Table 2 on page 15.

Example of window limi

t switch:

Selecting relay 1 to follow pressure measurement and relay 2 to

follow measurement of pressure from barometer module 1. Two relay

setpoints are set for both relays.
