PROMPT CHOICE(S)
SPAUto A Batching mode, allowing the operator to press the START key once to
add multiple materials automatically
─ It allows SoLo (single setpoint-relay) or PAIRED (dual setpoint-
relays) setpoint(s).
─ In the SoLo mode. Targets 1 thru X represent the required
weight of each individual material.
─ In the PAIRED
mode , Targets 1 thru 4 represent the Bulk or
Fast-Fill Relays
─ Targets 5 through 8 are the slow or target.
─ Note the association of paired setpoints-relay:
 1-5  2-6  3-7  4-8
Always program the Bulk-Fast Fill Setpoint-Relays to a lesser weight
value than the complete material weight value
─ Configure the Target-Slow Fill Setpoint-Relays assigned to the
complete material weight value.
─ When using multiple materials, set the SdELAY (timer for start of
next material relays) in the IO Menu.
─ If a printer has been selected, an auto print occurs when target
value is reached.
─ SPAUto is not available in the gallons mode.
