The EBU batch controller can be quickly tested to ensure proper operation. Follow these steps to test system

1.	Turn power on to the system.
2.	Push "Stop" switch of emergency stop (this is to keep the relay (CR1) from energizing during test.
3.	Set 100 on the preset.
4.	Push reset start switch. (the LED display will show 00100)
5.	Open enclosure and put run/test switch (S10) in test position to generate a flow signal.
6.	Watch LED display. It should count down from 100 to zero. At zero the LED display will begin counting up and you will see the over-run indicator is now lit. When you reach the component failure alarm set point you will get an alarm condition indicated by light and buzzer. This can be cleared by pushing the alarm reset switch.
7.	This test shows that the batch system is loading the preset amount, counting down to zero, setting the over-run indicator, and energizing the over-flow alarm system correctly.
8.	Switch S10 is connected to a pulse generator operating at 3600 pulses per minute. You can test the optional scaler by:
	a. Pushing power “off” then power “on” to clear the display.
	b. Push the test switch S10 for 1 minute.
	c. Read the amount on the LED display. You can stop the over-flow alarm by pushing the alarm reset switch.
	d. The amount on the LED equals.

The EBU (Electronic Batching Unit) is a solid state predetermining batch control system. It is equipped with a 5-digit preset, a 5-digit LED display and a 6-digit totalizer (electromechanical non-reset). When the EBU is reset the preset amount is transferred to the LED display and the control relay is energized. In the field a flow element sends digital pulses to the EBU, where they are filtered, scaled if required, and then processed. The processed pulses are then used to decrement the LED display (counts down) and are also divided by 10 and used to increment the totalizer (counts up). When the EBU reaches the floating zero set point the control relay is released.

Standard features include component failure alarm, over-run indicator, battery back-up with indicator, floating zero and membrane switching with all provided in one of two splash-proof enclosures.

The EBU is designed for batch control in areas where accidental splashing or hose-down may occur. We do not recommend hosing down any electrical equipment.
