BE1-11m Contact Inputs and Outputs
1. The relay trouble alarm disables all hardware outputs.
2. The programmable hold timer is active.
3. The select-before-operate function overrides a virtual output.
Figure 4-4 shows a diagram of the contact output logic for the general-purpose contact outputs. The
OUT1 relay closes when the 50-1 element is in a trip condition.

Figure 4-5 illustrates the contact output logic for the failsafe alarm contact output when OUTA is normally
closed (style xxxxxxx2xxxxxx). The OUTA relay closes when the 50-1 element is in a trip condition.

Relay Trouble Alarm Disable
All internal circuitry and software that affects how the BE1-11m functions is monitored by the continuous
self-test diagnostics function of the relay trouble alarms. A detailed list of relay trouble alarms is provided
in Table 4-3. If any one of these points asserts, the failsafe alarm output relay de-energizes and
closes/opens (depending on style number) the OUTA contact, the front-panel Relay Trouble LED lights,
all output relays are disabled, logic OUTA is set, and the BE1-11m is taken offline. The relay trouble
alarms function is not programmable.
