7.2.3.2.1 Stuck Valve Alarm
NOTE: This feature requires that the bypass sensor be relocated into the main plumbing
assembly instead of in the bypass plumbing branch so that it can monitor the temperature
of the incoming supply stream when the bypass is not active. The controller will monitor
the gas bypass sensor during and after filling.
When the freezer is supposed to be filling, if the controller does not see an appropriate
decrease in temperature, within the delay time entered in the menu, a stuck closed valve
alarm will be initiated. After the freezer is supposed to have stopped filling, if the
controller does not see an appropriate increase in temperature, within the delay time
entered in the menu, a stuck open valve alarm will be initiated.
The menu pages are in the hot gas bypass menu within the Add On menu. This will allow
enabling and disabling of these alarms and setting the time delays. These alarms are
enabled together. They cannot be selectively enabled / disabled.
The event code for the stuck closed alarm is “SC”
The event code for the stuck open alarm is “SO”
Refer to the Hot Gas Bypass Settings 7.2.3.2 (page 58) to change Stuck Valve Alarm
settings.
