What is the RML-500?
The RML-500 is a wireless leading-edge dimmer module suitable for
use with mains voltage tungsten lighting and low voltage tungsten
with leading-edge dimmable transformers.
●RML-500 modules are not generally recommended for use
with LEDs.
●RML-500 modules can be controlled by any Rako device that
transmits wireless messages.
Loadings
Minimum
20W
Maximum
500W
Low-voltage transformer
loads
450W (de-rate by 10%)
Mains voltage LEDs
Not Recommended
NB
RML-500 Manual Version 2.0.0
Derating is a precaution to account for varying characteristics in the lighting loads; this can
include inrush currents and higher ambient temperatures, as well as recommendations from
3rd party lighting manufacturers.
Installation
Installation should only be carried out by a competent electrician.
●RML500 modules should be mounted in areas that are adequately ventilated, dry,
and outside of any enclosed metal casings that may interfere with the wireless
signal.
●Modules should be mounted vertically, with the terminals at the bottom, or
horizontally.
●While the modules are designed to be maintenance-free, they should be mounted
in an accessible location should investigation or re-addressing of the units be
necessary.
●Ensure that the cable clamp is fitted tightly to secure the cables.
STEP 1:
Remove the cover and
cable clamp
STEP 2:
Insert the supply IN
conductors as well as the
load OUT conductors.
STEP 3:
Replace the cable clamp,
ensuring the cables fit
securely underneath
STEP 4:
Replace the cover

Initial checks
●When power is initially connected to the module, the load should power up to full
brightness.
●The clear button can be used as a manual on/off switch to test the circuit.
●The internal LED behind the clear button will flicker when the module receives any
Rako wireless message and is a useful diagnostic indicator. The LED feedback
becomes inactive after 20 minutes to avoid a nuisance light spill but can be
re-activated by pressing the clear button.
Programming the RML-500
Once the RML-500 has powered up and has been tested working with the setup button, the
device is ready to be programmed. For instructions on how to program the RML-500, see the
Wireless Module Setup Guide.
Appendix 1: LED Diagnostics
Wireless Range
LED Pulses
Description
Good wireless reception
When the unit is receiving
successfully, there will be
four rapid pulses on the LED
when any wireless message
is sent.
Bad wireless reception
When the unit is out of
range, there will be
intermittent pulses on the
LED when any wireless
message is sent.
NB
It is recommended to install
a wireless repeater
(WRB-100) if you are
experiencing intermittent
wireless range.
Should the module not respond to any of the above, check the supply voltage.
