G e n e r a l i n fo r ma t i o n :
ECP-024 is intended to be used with EMERSON’s EXD-U01/U02 Universal Driver
Module and/or EXD-SH1/2 Stand Alone Superheat controller.
In case of power failure, ECP-024 insures that the valve is driven to the shut-off
position. ECP-024 can be connected to two EXD-…
S a f e ty i n s tr 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 temperature, voltage and
current.
•
Before installation or service disconnect all voltages from system and device.
•
Ensure that design, installation and operation are according to European and
national standards/regulations.
•
Do not operate system before all cable connections are completed.
•
Disposal: ECP-024 contains lead acid gel rechargeable battery Electrical and
electronic waste must NOT be disposed of with other commercial waste.
Instead, it is the user responsibility to pass it to a designated collection point
for the safe recycling of Waste Electrical and Electronic Equipment (WEEE
directive 2012/19/EU). For further information, contact your local
environmental recycling center.
M o u n t i n g l o c a t i o n / I n s t a l l a t i o n :
•
Protect ECP-024 against sunrays, heat and moisture.
•
It is intended for installation in electrical switch
board/cabinet/box.
•
On vertical walls, with output connectors on top
side.
•
ECP-024 is delivered with bracket suitable for
mounting on DIN-Rail. Hang device above DIN-
Rail and push down- and backward until it snaps
completely and hold by DIN-Rail.

•
Ventilation of electrical switch board/ cabinet /box
(natural or forced) is recommended in order to
reduce temperatures and consequently not to reduce
the life expectancy of the battery.
•
Electrical Terminals K09-P00 (Part No. 804560) are
required.

•
It is mandatory the external grounding backside of ECP-024. (see Fig.1)
•
Use a class II category transformer for 24 VAC power supply. Do not ground the
24 VAC line.
•
See also operating instruction of Emerson EXD-U... and EXD-SH1/2.
•
It is recommended to supply the ECP-024 from same source (e.g. transformer) as
the connected driver/controller.

S e r v i c e :
•
It is recommended that ECP-024 to be checked for proper function and life of
rechargeable batteries during regular system inspection. It is advisable to add the
following procedure to the service handbook of system/unit.
T e s t o f b a t t e r y h e a l t h :
•
Disconnect the wires from ECP-024.
•
Connect a standard 22
Ω
resistor with minimum 15 W capacity to one of output
power and a DC-voltmeter as shown in Fig. 4.
•
Apply supply voltage 24 VAC to ECP-024 and measure the output power voltage.
It should be approximately 18.5 VDC.
•
Disconnect the supply voltage 24 VAC from ECP-024 and watch the output
voltage. Power output must maintain at 18 VDC for minimum 5 seconds.
•
ECP-024 always interrupts power output after 15 seconds when the supply voltage
24 VAC is disconnected.
B a t t e r y r e pl a c e m e n t i n s t r u c t i o n :
•
In case of battery life end, follow the following procedures for replacement of both
batteries at the same time:
1.
Disconnect the power and pull all green terminals from housing.
2.
Unscrew both black plastics covers with star-key T-10 and remove them. (Fig. 5)
3.
Pull out carefully the electronic board from right side. (Fig. 6)
4.
Disconnect the connectors of each battery from the electronic board and remove
the soft dividing plate as well as both old batteries from the housing (Fig. 7)
5.
Place carefully the new batteries inside of the housing, in the same position and
insert the soft dividing plate after batteries. (Fig. 8)
6.
Connect the new batteries to the electronic board (Fig. 9)
7.
The electronic board must be inserted in the two internal slots of housing
(Fig. 10).
8.
Put back the cover plates, press them firmly to their place and tighten with screws
Ensure, that the small grey soft pads are placed correctly in the middle of the
black cover plates. (Fig. 11) Then connect all previously removed terminals and
attach by sticker the date of battery change.
9.
Check the functionality of ECP-024 device like under point “
Test of battery
health”.
