CT Input/Potentiometer
When
using the HBA function on the E5EK-AA2 Controller
, connect CT input (CT) to
terminal numbers 15 to 17. When monitoring the valve
opening
on the E5EK-TPRR2 Controller
, connect
the potentiometer (PTMR) to terminal numbers 15 to 17. Connect each of these inputs as
follows:

s Manual (H88/H89/H90)
. For
details
on the potentiometer
, refer
to the
Instruction Manual
for the valve connected to the Controller
. The variable resistance range is 100
Ω
to
2.5 kΩ.
Event Input
Connect
event inputs 1 and 2 (EV1/2) to terminal numbers 18 to 20. However
, note that terminal numbers 18 to 20 cannot be used on Control
-
lers
with a communications function. Connect the event inputs as follows:

Contact input
ON: 1 kΩ
max., OFF: 100 k
Ω
min.
No-contact input
ON:
Residual voltage 1.5 V max.,
OFF:
Leakage current 0.1 mA max.
Polarities during no-contact input are as follows:
