6.5 Mode 2 - 4-20 mA input -
In this mode, the on-time of the cycle will
automatically adjust to match the received mA input value. When the mA
input value is equal to the programmed maximum, the pump will run
continuously.
Four values must be programmed:
1)
ON-T
= The amount of time the pump will run, per cycle, when the
minimum mA value is received. (Typically programmed to zero)
2)
mA minimum
= The mA input value that will result in the on time (
ON-
T
). (Typically programmed to 4 mA)
3)
TOT-T
= The total cycle time.
4)
mA maximum
= The mA input value that will result in the pump running
continuously.
Example:
ON-T setting = 0 seconds
mA minimum setting = 4mA
TOT-T setting = 8 seconds
mA maximum setting = 14.8mA
