Alarm Configuration - FULTON Vantage VTG Series Installation And Operation Manual

Alarm Configuration


Monitor Alarm: The monitor alarm is triggered in the event that the ModSync is not receiving the main gas valve
input back from the boiler. If the input is not received within a specified amount of time, this alarm is triggered to
indicate a safety limit at the boiler is preventing it from operating and can be configured to retry the boiler after a
user defined amount of time.

Boiler Alarm Delay: The boiler alarm delay will prevent nuisance alarms by making sure the alarm is on
consistently before locking the boiler out at the ModSync.

Sensor Alarm Delay: The sensor alarm delay will prevent nuisance alarms by making sure the sensor is
out of range for an extended period of time before triggering the alarm at the ModSync.

Boiler Enable After Alarm Clear: When enabled the ModSync will automatically enable a boiler if the
boiler alarm is cleared at the boilers flame programmer. When disabled the boiler alarm will need to be
cleared at the boilers flame programmer and then the user will need to enable the boiler manually at the
ModSync before the ModSync will bring the boiler back into the sequence.

Clear Alarm History: Selection that will clear the all alarms in the ModSync alarm history.

Monitor Alarm: The monitor alarm is defined as follows. The ModSync will send a heat demand to the
boiler. The ModSync then waits for confirmation that the boiler is running by monitoring the gas valve
signal from the boiler. During this time the Monitor Alarm timer is running. If the Monitor Alarm Timer
finishes before the gas valve signal is read, the ModSync will place the boiler into a Monitor Alarm state.
This alarm condition is an alarm at the ModSync only and will not show as an alarm at the boiler. It is
important that the Monitor Alarm Time Delay is long enough to allow the boiler to complete purge and
ignition and enter a run state. The Monitor alarm is used to indicate a non-alarm condition that could be
preventing the boiler from running such as an operating limit, low water condition, or other limiting
device that could prevent the boiler from running but the ModSync may not see.

Monitor Alarm Retry: If Enabled, when a boiler is locked out on a Monitor Alarm the ModSync will
automatically clear the Monitor Alarm after the adjustable time delay. This is to allow the boiler to rejoin
the sequence if an auto reset limit is the reason for the boiler being locked out on a Monitor Alarm
condition.
