Logical 'Or' Function; Logical 'And' Function - SMS ControlMate User Manual

CONDITIONAL OPERATIONS
In some situations, you may need to control equipment when two separate events occur –
either together (AND) or separately (OR).

LOGICAL 'OR' FUNCTION

To combine two separate input trigger events in an either-or arrangement, there are three
possible solutions depending on ow you need to control the target device.
INPUT-OR – allows two or more contact closure sources to be paralleled to a single input –
that either contact will cause the input state to change. The input conditions apply as
normally.
OUTPUT-OR – one possible situation is that two relay outputs are configured for different
operation (e.g. steady, flashing or pulsed), and under different circumstances will control the
same target device – perhaps a sign, or siren...
To achieve this, simply parallel the two output relays to the target device so that either relay
will activate the equipment.
xxCMD-OR – within the ControlMate unit, more than one input (perhaps with different input
state conditioning), can be configured (using
function. Hence if either of the inputs are asserted, the command will execute the same
command.
In this case, all input conditions are observed for each input individually – as are all output
settings for the nominated relay outputs.

LOGICAL 'AND' FUNCTION

To control a device when two trigger events are 'true', use the following method.
OUTPUT-AND - where two or more relay outputs are wired sequentially to close a circuit
only when both relays are active.
The relay outputs may still be configured to operate with any of the ControlMate functions,
but the target circuit will only be 'true' when all input, map and output conditions are met.
