rELY Mode Relay Mode: The behavior of each relay can be modified to support a variety of applications. These
include valve and indirect pump control as well as positive shutdown. Other modifications can be
made to a relays behavior to support remote horns. See below for complete details. The Group ID
shown corresponds to the Relay Output Number.
NornaLLY Normal Contact State: A relay can be configured as Normally ON to support positive shutdown
applications. In the non-alarm, non-action state, the relay output is energized resulting in the
Normally Open (NO) contacts closing and Normally Closed (NC) contacts opening. When an
alarm or other programmed action occurs that is assigned to the relay output, it is de-energized
resulting in NO contacts opening and NC contacts closing. ALL Relay Outputs are de-energized
when the TMS loses power or is powered off. Any external equipment monitoring the TMS or
being controlled by the TMS would behave as though the Relay Output was in the Alarm State.
Entry Type: select list
Range Limits: Off, On
Default/Initialized value: OFF
FP Ack Front Panel Acknowledgment: Primarily used to support remote horns. When an alarm condition
occurs that activates the relay output, the user would typically press any button on the TMS to
Acknowledge the Alarm. When enabled, this setting allows that acknowledgment to also return
the Relay Output to its Normal Contact State.
Entry Type: select list
Range Limits: No, Yes
Default/Initialized value: no
DeLay Delay: Primarily used to support remote horns. When an alarm condition occurs that activates
the relay output, the specified time delay determines when the Relay Output returns to normal,
effectively acknowledging the remote horn. Choosing NONE disables this feature.
Entry Type: select list
Range Limits: None: Disabled
1-9 minutes: Auto-Acknowledged after defined time delay.
Default/Initialized value: none
