3-10 Setup Procedure For The Batcher (continued)

MENU ITEM 8 ALG OUT
This section is for models of the batcher with the analog output feature. The Analog Output
card is a (0 - 20) or (4 - 20) mA current sink. The low (0mA) or (4 mA) and high (20mA)
settings may be set at any range. Attempting to set the high setting lower than or the same as
the low setting will display the warning message HIGH

≤

LOW and send the unit back to the

low setting section of the routine. The unit will not exit the ALG OUT routine until a proper
setting has been entered. If the displayed rate is below the 4 mA setting, the current driver will
stay at 4 mA. This allows for offsetting the low end of the output signal. If the displayed rate
exceeds the 20 mA setting the current driver will stay at 20 mA.

Note: The current sink follows (tracks) the display.
The Analog Output option is not available on Square Law Analog Input units.
