Table 2-1. BE1-25A, Controls and Indicators (Refer to Figures 2-1 and 2-2)
Locator A - GENERATOR SELECT Control
When the Test Module is in the test position (as shown in Figure 2-2), this control selects one of the six
possible generator operation times that are stored in the memory of the MCU Sync module. This
selection process allows the stored constant for a particular generator to be employed as a reference
for test purposes. This control has no function when the Test Module is in the operate position (as
shown in Figure 2-1.)
Locator B - Test Jacks
When the Test Module is in the test position (Figure 2-2), the tip jacks facilitate testing in the following
described manner. When the Test Module is in the normal position (Figure 2-1), certain jacks serve as
monitoring points as described in the following paragraphs.
Starting from the top, the seven pairs of jacks are:
1. BUS Voltage. When the test module is in test position, a simulated bus voltage can be injected
for test purposes. In normal position, monitors the bus voltage.
2. GEN (Generator) Voltage. When the test module is in the test position, allows a simulated
generator voltage to be injected for test purposes. In normal position, allows the generator
voltage to be monitored.
3. POWER. When the test module is in test position, allows the operating power to be supplied to
the BE1-25A relay. In the normal position, allows the supply voltage from terminals 21 and 22
of TB1 to be monitored.
4. 52b. When the test module is in the test position, provides a means of simulating a 52b contact
closure (by applying a jumper or closing a switch across these jacks). In the normal position,
allows the 52b contact input to be monitored. (Measures approximately 100 Vdc when the 52b
contact input is open, 0 Vdc otherwise.)
5. GF>BF. When the module is in the test position, provides the input terminals for a simulated
GF>BF contact closure. In the normal position, these jacks have no function.
