G e n e r a l i n f o r ma t i o n :

EC3-X33 is a universal superheat controller in conjunction with EMERSON

Electrical Control Valves EX4…EX8 and FX5…FX9.

Note: This document contains short form instructions for experienced users.

S a f e t y i n s t r u c t i o n s :

• 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.

• Do not exceed the specified maximum ratings for pressure, temperature,

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-X33 series contains

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.

M o u n t i n g p o s i t i o n :

The EC3-X33 is designed to be mounted onto a standard DIN rail. Mounting

position: on vertical walls, with stepper motor connector on top side only.

M o u n t i n g o f E C D — 0 0 2 :

• ECD-002 can be installed at any time also during operation.

• ECD-002 can be mounted in panels with

71×29 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.

!

E l e c t r i c a l I n s t a l l a t i o n :

• 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.

• 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

rd

controller(s) and for 3

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.

• Vacuum the entire refrigeration system

• Note: EMERSON Electrical Control Valves EX4…EX8 and FX5…FX9 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.

Note: When multiple alarms occur, the highest priority alarm is displayed until being cleared, then the next highest alarm is displayed until all alarms are cleared. Only

then will parameters be shown again.

C h e c k i n g s y s t e m o p e r a t i n g c o n d i t i o n s :

The data to be permanently shown on the display can be selected by the user (parameter ┌┘1). It is possible to temporarily display other values. However this function is

not available in an alarm condition. The display will show for one second the numerical identifier of the data (see ┌┘1 parameter) and then the selected data. After 5

minutes, the display will return to the value selected by parameter┌┘1.

Symptom

Operating superheat is several degrees higher or lower than

set-point

Operating superheat is too low i.e. compressor wet running

Valve is not fully closed

Instable superheat (hunting)

Valve opens when EC3 commands to close and vice versa

EX8 is not able to open at high differential pressure

Superheat set-point is shifting after several months of

uninterrupted operation or permanent jumper of 24 V digital

input

Incorrect signal from pressure or

temperature sensors

1- Incorrect wiring of EXVs

2- Defective sensors

1- The digital input is ON (24 V)

2- Wrong setting of parameter ut.

Evaporator is designed to operate at

higher superheat

Wrong wiring between EC3-X3…

and valve

Wrong setting of parameter ut

Stepper motor driven valves require

synchronization

www.emersonclimate.eu

Operating instruction

Check wiring connection and measure the signal 4…20 mA

Check wiring connection and measure the resistance of sensor

Check wiring connection and measure the resistance of winding

Battery potentially does not have enough charge to close valve in

case of main power supply interruption. May occur temporarily

with new controllers or after long storage but should disappear

when battery is charged sufficiently. If Ab remains active even

when battery is charged, battery may be defective and should be

replaced. (Replacement kit: 807 790).

Data send to the display is out of range. Check temperature and

pressure sensor.

Check Cable and plug connection between EC3-X3… and

ECD-002

Cause

1- Check the sensors

2- Make sure ECN-N60 temperature sensor is used

3- For optimum accuracy, please use:

4- Make sure the sensor cables are not installed along with other

high voltage cables

1- Check the wiring

2- Check the sensor

1- Valve is shut off only when the digital input is turned off (0 V)

2- Check the setting of parameter ut

Increase the superheat set-point

Correct the wiring

Check the parameter ut. (Larger valve requires higher torque and

higher current)

Do not apply permanent 24 V digital input. Interrupt digital input

once every week for 5 seconds if compressor never stops.
