Basler Electric BE1-64F - Manual (Page 14)

Locator Description
C Inhibit Status Indicator. This red LED lights when the Block input is energized and BE1-
64F tripping is disabled.
D Alarm Output Indicator. This red LED lights when the relay senses less than 20 k
Ω of
resistance from the machine field to ground and the Pre-Alarm output contacts close. This
function may be disabled by a user-adjustable jumper located on the draw-out printed
circuit board. See Section 4, Installation for the jumper location and jumper placement
instructions.
E Trip Output Indicator. This red LED lights when the relay senses less than 5 k
Ω of
resistance from the machine field to ground and the Ground Trip output contacts close.
F Target Reset Pushbutton. This control is pressed to reset the latching Trip Target indicator
(locator G) after a ground in the machine field circuit has been removed.
G Trip Target Indicator. This red indicator latches on when the Ground Trip output closes
due to a ground in the machine field circuit. Target status is maintained when relay
operating power is removed. When relay operating power is restored, the Trip Target LED
indicates the target status prior to the removal of operating power. The Trip Target
indicator is reset by operating the Target Reset pushbutton (locator F).
H Trip/Test Pushbutton. Simultaneously pushing the two Trip/Test pushbuttons (locators A
and H) causes the Ground Trip output contacts to close, the Pre-Alarm output contacts to
close, the Trip Output indicator (locator E) to light, the Alarm output indicator (locator D) to
light, and the Trip Target indicator (locator G) to latch on. This control is not provided on
BE1-64F relays with part number 9367200104.
