5.9Battery Temperature Probe Installation

The optional temperature probe is used to monitor the battery string temperature. To get the most representative temperature measurement, the probe should be placed in contact with a battery cell that is centrally located. The probe should be placed directly in contact with the cell (not the frame surrounding the cell). Generally, the cell cover can be used; be careful not to allow the probe body to touch the terminals.

1)Plug the connector end of the temperature probe into J5 the control unit interface card in the base power bay.

2)Route the cable as required to position the probe on the selected battery cell

3)Remove the adhesive protection strip from the probe body and press the adhesive side of the probe on the battery cell cover.

5.10 Power-Up and Checkout

Before initiating power-up and checkout, ensure that the following conditions exist:

1)Make sure that the external circuit breaker protecting the cables from the battery to the power plant is turned OFF (the battery cables should be connected to the power plant, but the battery should not be connected).

2)Make sure that all load circuit breakers are turned OFF and all load distribution fuses are removed.

3)Verify that all rectifiers have been installed.

5.10.1Apply AC Power

Turn on the circuit breakers that supply ac power to the rectifiers in the MX28B dc power plant. The main screen should appear on the control unit display (see Figure 5-11). The display on the control unit is a 2-lines by 16-characters display. The cursor cycles below the characters of the active selection on the display. Information shown in the second line of Figure 5-11 that extends beyond 16 characters (to the right of the “S” in “ALARMS”) can viewed on the control unit display by using the scrolling controls (refer to Section 6 for operation of the control unit).

NOTE: When ac power is initially applied, there is a 60-second period during which no alarms are reported.
