When this setting is enabled, only the fast feed relay is initially energized. The fast feed
relay is de-energized and the slow feed relay is simultaneously energized when the
weight reaches the preset minus the dribble value. The slow feed relay is de-energized
when the preset weight minus the preact is reached.
F2.9 Invert Relays
If enabled the On/Off function of the output relays (J7) is reversed. The relays will be off
below the presets and turn on as they are reached. Exception: relays K7 and K8 (fill
complete and zero interlock) are not affected by this setting.
F2.A Parallel Feed
Allows presets to operate independently of each other. In this mode presets can be set to
any value. It is not necessary for each preset to be of a higher value than the one before it.
Each output will operate as if it were the only one. If disabled the outputs operate
sequentially. First preset one (1) and then preset two (2), then preset three (3), etc. The
value of each preset must be higher than the one before it for the system to operate
properly.
F3.0 Baud Rate
Used to set the baud rate (speed) of all serial ports. Serial data is available at TB2 and J6
on the mother board. This must be set the same as the device to which it is connected.
F3.1 Parity
The checksum bit used in serial communication. It can be even, odd or none. This is also
where you would set the number of data bits (7 or 8). This must be set the same as device
to which it is connected.
F3.2 Checksum
This checksum is for an entire data stream (one line of print, etc.) as opposed to parity
which is for one character. It is used during communications to verify that the received
data contains no errors.
F3.3 Delay After Carriage Return/Line Feed
Used to cause the system to pause after a carriage return. Needed with some devices to
allow the data which was just sent to be processed (such as some older printers without
buffering). If not needed set to 0 as it slows down the system.
