· When using the HBA function on the E5AK-AA2 controller, connect CT
input (CT) to terminal Nos.15 to 17. When monitoring the valve opening
on the E5AK-PRR2 controller, connect the potentiometer (PTMR) to

For details on CT inputs, see Appendix, About Current transformer.
· For details on the potentiometer, see the Instruction Manual for the
valve connected to the controller. The variable resistance range is 100
W to 2.5 k W .
· Connect an input (RSP) to be used as the remote SP to terminal Nos.21
and 22.
· Only 4 to 20 mA inputs can be connected. Connect the input as follows:
