Automatic Run Test — The 50BV,XJ unit controls are programmed with an automatic run test that checks connection and operation of major components. To perform the run test:

Verify that the control display (LID device/System Monitor) interface cable is connected to internal jack on main controller; that the fire alarm/shutdown switch input (FSD) has a factory jumper or field input; that Bypass (if installed) is set in the DRIVE position; and that the Local/Off/Remote switch is set to the REMOTE position.

NOTE: When the Local/Off/Remote switch is in the REMOTE position, the controller time schedule is pre-set (from the factory) as unoccupied. This means that the unit will not turn on until the run test is enabled. However, if the controller schedule has already been modified in the field, and the current time of day is occupied, then the supply fan will start. The run test will shut the fan down when it

begins. The run test will complete and then the supply will automatically restart.

NOTE: If the Local/Off/Remote switch is in the OFF posi- tion, it is normal for the red alarm light on the display panel to be lit, indicating that the unit is disabled.

NOTE: If the red light stays on when the switch is moved to REMOTE, or if any other problems occur during the run test, refer to the Troubleshooting section of this manual.

To perform the Run Test:

1.Turn unit power on.

The LID display will show the controller identifica- tion, time and date (Fig. 5):
