manual.
Use only Edwards accessories.
User requirements
 The user must be familiar with the function of the device; read and understand the
operating instructions before connecting and operating the device.
 The user should consult local, state, and national agencies regarding specific
requirements and regulations for devices with wireless transmission capability.
 For any questions regarding safety, operation and/or maintenance, the user should
contact the nearest representative.
Restrictions of use
Hazards in the event of intended use
When handling the ELD500 RC:
Note:
The ELD500 RC must only be connected and operated by properly trained personnel.
WARNING:
Danger in explosive environments. The ELD500 RC may only be used away from explosive
environments.
WARNING:
Possible interference with pacemakers. The performance of pacemakers may be affected
by the magnets on the back of the ELD500 RC. Observe the distances indicated by the
pacemaker manufacturer.

Description
Use
The ELD500 RC Wired and ELD500 RC Wireless have been designed to operate the ELD500
leak detector.
The ELD500 RC is accommodated in a robust housing the shape of which enables ergonomic
working. Magnets on the underside of the unit enable it to be attached to horizontal or
vertical metal surfaces.
CAUTION:
Possible risk of damage. The ELD500 RC may be damaged beyond repair by immersing in
liquid. Do not switch on the ELD500 RC if liquid has penetrated the unit.
Contact the Edwards Service Department.
CAUTION:
Possible risk of damage. The ELD500 RC may be damaged by being stored in unfavourable
conditions (too damp, too hot, too cold, too high above sea level) for months or years (see
Technical Data).
If the ELD500 RC has been stored under such conditions, leave it switched off and contact
Edwards Service.
CAUTION:
Possible risk of damage. The ELD500 RC may be damaged by improper transport.
Always transport the ELD500 RC in its original packaging.
Note:
Clean the plastic housing of the ELD500 RC, the front foil and the display using a soft cloth,
moistened with some water or soap suds. Do not use any solvents.
Note:
The performance and reliability of the ELD500 RC can only be guaranteed if it is operated
under the specified conditions of use (see Technical Data).
Note:
Any changes made to the ELD500 RC by the user may result in a violation of statutory
provisions or may affect the EMC properties and safety of the product. Edwards does not
accept any liability for the consequences of such changes.

D13510840D - RC Remote control
Page 6
The ELD500 RC Wireless version enables remote operation up to a distance of 100 m,
depending on reception conditions. The integrated rechargeable battery enables over 8
hours of operation, depending on the battery level.
The ELD500 RC Wired version enables remote operation of the leak detector in question up
to a distance of 28 meters using a connection cable.
The leak rates can be displayed in digits or in a curve on the 3.5" colour display.
Measured values of up to several hours of recording can be stored in an internal memory. The
data storage interval is adjustable. The data can easily be downloaded to a USB stick via the
integrated USB interface to save it.
An internal trigger can be set to provide a warning if the maximum leak rates are exceeded.
An optical warning is shown on the display and an acoustic warning signal with variable pitch
proportionally to the leak rate is sounded on the integrated loudspeaker or the connected
headphones.

Installation
Connection to the leak detector
ELD500 RC Wireless
The ELD500 RC Wireless is connected to the leak detector by means of a wireless data
connection.
Connect the leak detector to the radio transmitter for this purpose (see Connecting the radio
transmitter to the leak detector).
The ELD500 RC Wireless is shipped set-up for connection with the supplied radio transmitter.
This way, the connection is immediately established upon turning the unit on.
Alternatively, it can also be connected by means of the enclosed cable, similar to connecting
the ELD500 RC Wired. In this case only one connection cable must be used with the ELD500
RC Wireless, not more.
ELD500 RC Wired
The ELD500 RC Wired is connected to the leak detector by connecting the enclosed
connection cable to the RJ25 socket (see Figure 5).
Connecting the radio transmitter to the leak detector
Connecting the radio transmitter for the ELD500 RC Wireless:
Use Velcro to position the radio transmitter (1) in a suitable location on the leak detector so
that there is a direct line of sight between the antenna and the remote control.
Connect the connecting cable of the radio transmitter to the RJ25 socket of the leak
detector (2).
Note:
To extend the wireless operating range an extension cable also can be used to position the
radio transmitter away from the leak detector, if reception is poor (e.g. at the ceiling of the
room).

Inputs and outputs
The inputs and outputs of the ELD500 RC have covers to prevent large dirt particles and
moisture from penetrating.
Note:
The operating range of the radio transmitter will be affected by metal objects if it’s near, avoid
installing the antenna near such objects.

Note:
The IP42 safety class can only be guaranteed if the covers are closed.
Note:
Leave the protective plug in the socket when the cable is not connected.
Note:
We recommend only inserting and removing the RJ25 plug as often as is necessary for
operation.
Note:
Fold the protective strip upwards before connecting a plug (not shown).
1 USB connection
Insert the USB stick (FAT formatted) to record data.
2 3.5 mm jack for stereo headphones
Standard stereo headphones with a 3.5 mm jack plug and
> 2 x 32 Ohm impedance can be connected to the jack.
If the headphones are inserted, the volume of the
integrated loudspeaker is automatically lowered.
