OEM SHC CONTROLLER – INSTALLATION INSTRUCTIONS
Buffer Battery
A 24 V emergency battery module with internal charge control
can be connected to the controller terminal 3 to enable safe
closing at power failure. 1 Ah is recommended.
The battery module provides power voltage only in the event
of a power supply failure (at terminals G and G0). If the micro-
processor detects that power is being fed in simultaneously
via terminals G and G0 and from the battery module, this is
recognized as a power supply failure.
INPUTS/OUTPUTS
General Information
The controller is equipped with removable screw-type terminal
blocks which allow the terminal assignment to be made
before plugging them into the unit and to be preserved after
unplugging them from a unit requiring repair or replacement.
Wiring the Inputs/Outputs
The screw-type terminals support wiring with flexible or
massive cables of 0.35 mm² up to 2.5 mm².
Two wires with a total thickness of 14 AWG can be twisted
together and connected using a wire nut (include a pigtail with
this wire group and attach the pigtail to the individual terminal
block). Deviations from this rule can result in improper
electrical contact. Local wiring codes may take precedence
over this recommendation. Wire to the terminal blocks as
follows:
1. Strip 5/16 in. (8 mm) insulation from the conductor.
2. Insert it at the required terminal location, and tighten the
screw to complete the termination. Fix the cable using
cable binders if required.

RS485
The controller provides an isolated RS485 communication
interface which is connected to terminals 9 to 11 (see Table
1).
The max. permissible number of devices simultaneously
connected to RS485 output is 32. The RS485 cable is of
impedance 120 Ohm with maximum length of 1000 m.
Connection via STP (Shielded twist pair) is recommended.

HARDWARE FEATURES

Stepper Motor Output
The controller is able to drive bipolar stepper motors with 12 V
or with 24 V supply voltage. The stepper motor is connected
to terminals 4 to 8 (see terminal assignment) with shielded
motor cable.
The proper operation of Alco EX7 and EX8 valves together
with this controller regarding EMC standards recommend
shielded motor cable and two windings together with 24 Vac
power lines on Wuerth Elektronik 7427137 ferrite.

Besides the Honeywell electronic expansion valve type EEV
(models EV2, EV3, EV4), the controller provides presettings
for the stepper motor valves listed in Table 3 with the cor-
responding parameters. These valves can be configured by
just choosing the valve type. Other valves which fit to the
above listed ranges of stepper motor parameters can be
configured manually.
