Configuring the MCT-MC
4.3.19 Output 3 Failure Transfer
The output 3 failure transfer setting is used to set whether the output should be on (1) or off (0) when there is
an input failure, i.e., sensor break. The setting applies to alarm output functions only.
4.3.20 Output 4 Function
The Output 4 Function selection is used to configure the loop control board output as an alarm, event or
retransmit output. The output selections are mutually exclusive, i.e., selecting one will turn off the others. Once
the desired function has been selected, press the “Done” button to set the output function and return to the
main Loop Configuration screen.
NOTE:
The output function must be set to match the type of output ordered on the loop control board. Relay,
triac and SSR output types are used for alarm or event outputs. The retransmission Vdc and mA
output types are used for process value or set point retransmit.
The
Alarm output
function activates the Alarm 3 configuration settings for assigning the type of alarm logic to
apply to output 4. When the alarm condition is active, the output will turn on.
The
Reverse alarm output
function activates the Alarm 3 configuration settings for assigning the type of alarm
logic to apply to output 4. The output will be normally “on” when this function is selected. When the alarm
condition is active, the output will turn off.
The
Event output
function allows the output to be turned on and off via an automatic program or manually
through the MC runtime application to act as a “soft” switch to turn system components on and off.
The
Retransmit process value
and
Retransmit setpoint value
functions allow the loop control board output
to retransmit the current input value or control set point to remote devices such as a chart recorder.
The
DC power supply output
function must be selected when the output type ordered for the loop control
board output 4 is a transmitter power supply.
4.3.21 Output 4 Failure Transfer
The output 4 failure transfer setting is used to set whether the output should be on (1) or off (0) when there is
an input failure, i.e., sensor break. The setting applies to alarm output functions only.
