Installation and Operating Instructions
FM unit for resistive loads
and electronic transformers
Art. no.:
492 AB o.A.
1. General description
- internal softstart / softstop depending on switch process
- various operational modes selectable via rotary switch
- various LED functions, settable via potentiometers
(only in combination with particular attachments)
- connection to remote station possible
- non-volatile stored switching times
- basic brightness setting!
(not available with all functions)
New load designation:
R = for resistive loads, light bulbs
C = for capacitive loads, electronic transformers
2. Installation
Work on 230 V mains may only be performed by trained and
authorised personnel. All such activities may only be performed
when mains voltage has been switched off.
This FM device is designed for installation in a Ø 58 mm
accessory box. It has a prescribed installation orientation (TOP
is marked) to ensure that the attachment will also be subsequently
mounted in its proper orientation. Setting the potentiometer or
the rotary switch is only permissible when the mains supply
voltage is switched off. The attachment used must be carefully
plugged into the appropriate socket when mains voltage is
switched off. Guide it carefully when plugging it in.
The following must be observed:
- prevailing statutes, standards and regulations.
- state of the art technology at the time of installation.
- the operating instructions for FM devices and attachments.
- the fact that operating instructions can only make general
reference to regulations but that these must then be
interpreted in conjunction with a specific system.
These devices may
not
be used in systems whose operation
could present a hazard to persons, animals or property.

The dimmer has electronic short-circuit protection. It cuts off
automatically upon the occurrence of a short-circuit condition
or overload. Once the short-circuit or overload has been re-
medied, the dimmer can be switched on again.
The dimmer is equipped with additional temperature protection.
After this protective circuitry opens due to excessive ambient
temperature, the dimmer will cool off over a period of time.
When it has cooled off sufficiently, the dimmer will automatically
be turned on again. Connecting an unsuitable load to the dimmer
will cause its temperature protection to open on a permanent
basis, i.e. taking the dimmer out of service!!
Ripple fluctuations on the mains voltage can become noticeable
as a flickering of attached lamps when dimming is set to low-
brightness values. The unit may produce a hum; this is caused
by the interference-suppression capacitor.
Neither of these characteristics represent a dimmer defect nor
grounds for complaint or claims.

4. Loads
Unbalanced loads should not be driven, i.e. only identical
transformers are to be connected in parallel; this is to ensure
that brightness remains constant in the lighting branch.
The transformer should have its nominal load and may not be
switched with a series-connected switch.
Electronic transformers may only be used if they are approved
by the manufacturer for trailing edge dimming.
Caution!!
-
Not
suited for electronic transformers only approved for
use for leading-edge dimming!
-
Do not use
with additional power stages!
- Reduces brightness with its own energy dissipation!
5. Derating dimmer output
When in operation, the dimmer becomes warm as a small
proportion of the connected load is transformed into heat.
The specified nominal output is based on the dimmer being
mounted in a massive stone wall.
If the dimmer is mounted in a wall of autoclaved aerated
concrete, wood, plasterboard or in a surface-mounted box,
the max. connected load must be derated by at least 20%.
This reduction is also necessary when multiple dimmers are
combined into a single system or when other heat sources could
lead to additional warming.

7. Remote station circuit
FM unit with remote unit 490N
Permissible attachment for the remote station:
Art. no.:
-
Tactile attachment for dimmer and switch,
xx.420.xx
For switching or dimming via a remote station,
input 1
of the
FM unit is to be connected via the remote station to the phase
leg L conductor. Here it must be ensured that the L conductor
for the FM unit is the same phase leg.
The remote station's control line should be routed at a distance
from load-carrying lines.
A maximum wiring length of 50 m to the remote station switch
should not be exceeded.
Caution!!
Remote station switches may not contain a glow
lamp light as this could cause malfunctions due to the sensitive
input! Illuminated switches may only be used if they have a
separate connection to the neutral (N) line.
8. Troubleshooting & remedies
Lamps flicker briefly:
- mains voltage fluctuations
- ripple pulses
The dimming function doesn't work:
- inadequate minimum load, increase the load
The dimmer switches without pressing the button:
- a remote station may have a glow lamp,
remove the glow lamp.
- short-circuit in the remote station's conductor
Lighting cannot be switched on:
- replace defective lamps
- repair short-circuit
- check wiring connections
- reset the protective switch
- replace defective dimmer
Attachment switch does not work:
- incorrect function is selected, check the rotary switch
- check potentiometer
9. Warranty
These operating instructions are an integral part of both the device
and our terms of warranty. They must be furnished to the user.
The technical design of the device is subject to change without
prior notification.
PEHA
products are manufactured and quality-checked with the
latest technology according to applicable national and international
regulations. Nevertheless, if a product should exhibit a defect,
PEHA
warrants to make remedy as follows (regardless of any
claims against the dealer to which the end-user may be entitled
as a result of the sales transaction):
In the event of a justified and properly-established claim,
PEHA
shall exercise its prerogative to either repair or replace the defective
device. Further claims or liability for consequential damages are
explicitly excluded. A justifiable deficiency is one in which the device
exhibits a structural, manufacturing, or material defect that makes
it unusable or substantially impairs its utility at the time it is turned
over to the end-user.
The warranty does not apply to natural wear, unintended usage,
incorrect connection, device tampering or the effects of external
influences.
The warranty period is for 24 months from the date of purchase
by the end-user from a dealer and ends not later than 36
months after the device's date of manufacture. German law is
applicable for the settlement of warranty claims.
