3.10 Logic Gates Set Up Group

Introduction
This Set Up Group is provided only as part of the Math Options package.
This group deals with various Logic Gates that are available for use in the controller. Up
to five different gates can be configured.
ATTENTION
If the controller is configured to use the same relay for more than one function, then the
following priority is used to determine how the relay functions: Control Outputs take
precedence over Alarms, which in turn take precedence over Time/Events, which in turn
take precedence over Logic Gate Outputs. For example, if you select the Loop 2 Output
Algorithm as Time Simplex (which uses Relay 3), enable Alarm 3 (which also uses
Relay 3) and configure a Logic Gate to use Relay 3, then the instrument will use Relay
#3 to perform the Time Simplex output and ignore the Alarm and Logic Gate functions.
Logic Gates are processed in numerical order. For example, if Logic Gate 2 and Logic
Gate 4 are configured in a contradictory manner, then Logic Gate 2 will take precedence
and Logic Gate 4 will be ignored.
Logic Gate Outputs configured for Relays will light an annunciator when active.
Outputs for Relay 1 through Relay 4 will light annunciators OUT 1 through 4. Logic
Gate Outputs for Relay 5 will light annunciator ALM 1.
