Merkur 2 ES.SM.R.C
* Both relay contacts are electrically isolated. Connecting the two contacts in series or in parallel is not permitted for safety reasons. Each contact must be evaluated
separately by the door controller. The initial state is only correct if the state of both relay contacts is the same. The door controller has to periodically verify this relay
output function according to the relevant standards requirements.
Combination of several Merkur 2 ES.SM for escape and rescue routes
According to AutSchR, signal sensors must fully release the escape route
without an explicit request, i.e. at any point across the full width of the door up
to at least 1.50 m before the door panels. This requires two sensors depending
on the door size. The following combination of two Merkur 2 ES.SM.R outputs is
the only approved option:
Control unit with two
Merkur 2 ES.SM.R.C
inputs for the
relay signal
Important:
All other combinations are not permitted! A separate input must be available for
each Merkur 2 ES.SM.F / Merkur 2 ES.SM.V if the door controller has a frequen-
cy or voltage input.

Sensor Configuration
The sensor can be configured in two ways:
→ With keys on the sensor (basic settings), chap. 5.1
→ With the remote control (complete setting options), chap. 5.2

Configuration with keys
General procedure
1)
Keep [<] and [>] pressed for a corresponding length of time; every 2 s the
green LED will flash once
2)
Frequency of the flashing green LED (1-9 times) indicates current parameter
level
3)
The parameter level can be decreased or increased with [<] and [>]
respectively
4)
Press [<] and [>] briefly to exit the programming mode (settings are saved)
