Load Trap

The Load trap is generated whenever the total input load on an infeed exceeds a preset threshold. Load traps include the reported input load, load status, Location of the Sentry, and identifier and name of the affected infeed.

Any error state generates a Load trap and triggers the trap timer. A new trap is generated at the end of every timer period until the Load returns to a non-error status.

Enabling or Disabling a Status trap

The Set Trap … Status command is used to enable or disable Status traps for a Tower, Infeed or Outlet.

To Enable or Disable a Status trap:

At the Sentry: prompt, type set trap (tower, infeed, or outlet) status, followed by the tower, infeed or outlet name, and on or off. Press Enter, or

Type set trap (tower, infeed, or outlet) status all, followed by on or off and press Enter.

Examples

The following command enables the Status trap for the first tower, using the tower’s absolute name:

Sentry: set trap tower status .a on<Enter>

The following command enables the Status trap for the tower named Florida_HQ_1:

Sentry: set trap tower status Florida_HQ_1 on<Enter>

NOTE: Enabling lower hierarchical traps automatically enables traps of higher hierarchical value: i.e. enabling an Outlet Status trap automatically enables the Infeed and Tower Status traps for that outlet. Conversely, if a Tower Status trap is disabled, all associated Infeed Status & Load and Outlet Status traps will be disabled.
