Section 26 • Remote Oil Cooler
Maximum Speed:
• This setpoint defi nes the maximum speed in per-
centage for Remote Oil Cooler VFD Fan at which it
should run for continuous step delay time to increase
Remote Oil Cooler steps. E.g. let's say setpoint is kept
at 95%. Then Remote Oil Cooler VFD fan will have to
run at speed of 95% or more to advance to next step.
Maximum Speed can be set as 100%, which is when
analog output (at which Remote Oil Cooler VFD fan
is connected) reaches to 20mA in its normal range of
4-20 mA

Minimum Speed:
• This setpoint defi nes the minimum speed in percent-
age for Remote Oil Cooler VFD Fan at which it should
run for continuous step delay time to decrease
Remote Oil Cooler steps. E.g. let's say setpoint is kept
at 5%. Then Remote Oil Cooler VFD fan will have to run
at speed 5% or less to advance to next step. Minimum
Speed can be set as 0%, which is when analog output
(at which Remote Oil Cooler VFD fan is connected)
reaches 4mA in its normal range of 4-20 mA
