Figure 18: EST3 rules for the SIGA-REL
Notes
• RESET rule: On reset, the prerelease circuit is forced to deactivate, which
also deactivates the release circuit. The system determines whether an alarm
is still present before making the decision to activate the releasing sequence
again. In this situation, the system delay (the time necessary to test and
analyze alarms) overrides the rule delay. When the system is reset and the
alarm restored, the SIGA-REL turns off both the prerelease and release
circuits (in that order).
• PRERELEASE rule: On alarm, the PRERELEASE rules activate the
prerelease circuits. These rules require the addition of alarm devices to the
panel configuration. Make sure that the object labels match the labels
assigned to them in the Object Configuration.
• AND GROUP RELEASE rule: When the AND_GROUP activates, the release
circuit is activated after the programmed delay, as per the rule.
• MANUAL RELEASE rule: If the manual release circuit on the SIGA-REL is
activated, the SIGA-REL independently activates its releasing circuits. The
MANUAL RELEASE rule forces the panel output to match the SIGA-REL
output.
• [LED1] and [LED2] require the addition of an LED module to the Cabinet
Configuration (Modules tab, operator layer). Make sure that the labels for the
LEDs match the labels assigned to them in the Object Configuration.
