General information:
EC3-P33 is the superheat controller for systems with flammable refrigerants
(A2L/A3) and able to drive EMERSON Valves EX4-7-…FLR via M12 Connector
ECV05A.
Note: This document contains short form instructions for experienced users.
Warning:
• EC3-P33 has a potential ignition source and does not comply with ATEX
requirements. Installation only in non-explosive environment.
• EX4-7…FLR are currently released for R290 in term of compatibility. The
other listed refrigerants are subject to qualification at later stage. No
warranty or product liability if EX4-7…FLR to be used with other
refrigerants stored in software of EC3-P33.
Safety instructions:
• Read operating instructions thoroughly. Failure to comply can result in device
failure, system damage or personal injury.
• According to EN 13313 it is intended for use by persons having the
appropriate knowledge and skill.
• Ensure that the system is correctly labeled with applied refrigerant type and
a warning for explosion risk.
• Do not exceed the specified maximum ratings for temperature (max.+60°C),
voltage and current.
• Before installation or service disconnect all voltages from system and device.
• Do not operate system before all cable connections are completed.
• Entire electrical connections have to comply with local regulations.
Note: The EC3-P33 series contains a VRLA battery = valve regulated rechargeable
lead-acid battery. The battery must NOT be disposed of with other commercial waste.
Instead, it is the user’s responsibility to pass it to a designated collection point for the
safe recycling of batteries (harmonized directive 2012/19/EU). For further
information contact your local environmental recycling center.
Mounting position:
The EC3-P33 is designed to be mounted onto a standard DIN rail. Mounting position:
on vertical walls, with stepper motor connector on top side only.
Mounting of ECD-002:
• ECD-002 can be installed at any time also during operation.
• ECD-002 can be mounted in panels with
71x29 mm cutout.
• Push controller into panel cut-out.(1)
• Make sure that mounting lugs are flush with
outside of controller housing
• Insert Allen key into front panel holes and turn
clockwise. Mounting lugs will turn and gradually
move towards panel (2)
•
Turn Allen key until mounting lug barely touches
panel. Then move other mounting lug to the same
position (3)
• Tighten both sides very carefully until keypad is
secured. Do not over tighten as mounting lugs
will break easily.
Electrical Installation:
• Refer to the electrical wiring diagram for electrical connections.
• Do not apply voltage to the controller before completion of wiring.
• Ground the metal housing with a 6.3 mm spade connector.
• Keep controller and sensor wiring well separated from mains wiring.
Minimum recommended distance 30 mm!
• Ensure that cables are not mounted near sharp edges.
• Use a class II category transformer for 24 VAC power supply. Do not ground the
24 VAC lines. We recommend using individual transformers for EC3 controller(s)
and for 3
rd
party controllers to avoid possible interference or grounding problems
in the power supply.
• Connecting any EC3 inputs to mains voltage will permanently damage the EC3.
• The use of the relay is essential to protect the system in case of power failure if the
communications interface or the ECD-002 are not utilized.
• If the output relay is not utilized, the user must ensure appropriate safety pre-
cautions are in place to protect the system against damage caused by a power
failure.
• In order to provide system protection in the event of power loss, it is recommended
to change the battery annually.

Preparation for Start-up:
• Vacuum the entire refrigeration system
• Note: EX4-7-…FLR are delivered at half open position. Do not charge system
before closure of valve.
• Apply supply voltage 24 V to EC3 while the digital input is 0 V (open). The valve
will be driven to close position.
• After closure of valve, start to charge the system with refrigerant.
• Start the system and check the superheat and operating conditions.
