G.1. Falcon-EM Relay Logic
Figure G.1 on page 215 contains the FMS relay control logic diagram described in the
following sections.
OR Gate 144 Input
The OR Gate can accept any of the High Level 2, Low Level 2 or digital alarms. This option is
configured on each input configuration page.
AND Gate 4 Input
The AND Gate can accept up to 4 alarms. These 4 inputs can be any of the analog level 1 or 2
alarms or any digital alarm. This option is configured on each relay configuration page.
OR/AND Gate3
This gate uses the OR Gate and the AND Gate as the inputs. This gate may be either an OR or
an AND gate and is configured on each relay configuration page.
On-Delay
This gate will delay the relay operation until the programmed time has expired. The time is
configured on each relay configuration page.
On-Duration/Latch
This gate controls how long the relay will stay activated after a valid alarm combination. A
positive number will allow the relay to stay on for a fixed number of seconds. A negative
number will keep the relay activated for that time after the alarm condition has returned to
normal. Zero will force the relay to stay active until the alarm returns to normal. The time is
configured on each relay configuration page. This gate can also be set for latching-the relay
will stay active until it is manually reset by a user.
