Table 2-1. BE1-60 Control and Indicator Descriptions
Locator Control or Indicator Description
A Differential Limit Switch This ten-position thumbwheel switch sets the maximum
allowable voltage difference between Circuit 1 and Circuit 2.
The switch letters (A through K, excluding I) correspond to the
percent of nominal circuit voltage as indicated by the chart on
the front panel. The Differential Limit Switch can be adjusted
from 5% to 50% of nominal in 5% increments.
B Target Indicators
(optional)
The BE1-60 may be equipped with two electronically latching
red indicators—one for Circuit 1 and one for Circuit 2. When a
fault occurs on Circuit 1 or Circuit 2 and the appropriate relay
output changes state, the corresponding target indicator
illuminates. Target indicators are manually reset by operating
the target reset switch (locator D).
C Output Test Pushbutton
(optional)
The BE1-60 may be equipped with two pushbuttons (Circuit 1
and Circuit 2) that can be used to verify operation of the relay
output contacts. The momentary-action pushbuttons are re-
cessed behind the front panel and are operated by inserting a
slender, non-conducting rod through one of the two panel
openings.
D Target Reset Switch
(optional)
The target reset switch is provided on BE1-60 relays
equipped with target indicators.
E Power Indicator This LED (light-emitting diode) lights to indicate that the relay
power supply is operating.
