Model RMI is a remote manual-control station with a toggle switch used to either increase or decrease the capacity
setting of the pump. The control panel is equipped with a meter that indicates the output of the pump as a percent of
stroke. See Figure 7 for wiring details, size, and other information.
This controller is a bridge balancing relay with ratio adjustment for automatic control of pump from a process instrument
that has a transmitting potentiometer. See Figure 8 for wiring details and mounting information.
This model is a proportioning bridge relay with ratio adjustment for automatic control of pump from a process instrument
that has DC milliamp output. The milliamp rating of this unit must agree with the DC input signal being applied. Wiring
details are shown in Figure 9.
Model A MI has a meter indicating pump delivery as a percent of stroke. It combines the features of the RMI model with
the features of the PRRA model. The manual-off-auto switch allows either manual or automatic operation. The wiring
diagram is shown in Figure 10.
This unit is also an automatic-manual controller like the AMI, but it combines the automatic function of the PRRA-MA
(milliamp input signal) with the RMI manual function. See Figure 11 for wiring and installation details.
