Handling and operation
Refer to Figure
1 RS-232 selector S1: "Modem" / "PC"
Signal selector S2 "Alarm": "on" / "off"
2 Modem reset button "Reset Modem"
3 RS-232 socket "RS-232"
4 Connection terminals for low-voltage:
Konnex bus "CE–", "CE+"; fault inputs "P1", "M", "P2", "M"
5 Konnex bus button: "Install"
6 LED for programming: "Prog" (red)
7 Connection terminals for mains voltage "AC 230 V"
8 LED for operation "On" (green)
9 LED for fault indication "Alarm" (red)
LED for operation
The green LED indicates the operating state of the central com-
munication unit:
• LED lit: Mains voltage present
• LED flashes: Communication via RS-232
The LED is also visible when the terminal cover is fitted.
LED for faults
The red LED next to the mains terminals (bottom) indicates the
fault state of the central communication unit:
• LED dark: No fault in the system
• LED lit: 1 or several Synco devices faulty
• LED flashes: Internal fault of the central communication unit or
fault at the fault inputs
The LED is also visible when the terminal cover is fitted.
LED for programming
The red LED next to the Konnex bus connection terminals (top)
indicates whether the central communication unit is in addressing
mode.
• LED dark: Normal mode
• LED lit: Addressing mode
The LED extinguishes automatically after the device address has
been adopted with the ETS (EIB tool software).
The LED is also visible when the terminal cover is fitted.
RS-232 selector S1
S1 is used to select whether the central communication unit at
RS-232 is connected to a modem (selector position
to a PC (selector position
Signal selector S2
S2 is used to select whether or not pending faults or system re-
ports shall be delivered to the message receiver (selector posi-
tion and respectively).
Konnex bus button
An extended press (>6 seconds) starts the search run, which
generates the internal device list.
For other choices regarding the creation of the device list, refer to
section "Commissioning", under "Creating the device list".
A short press (<2 seconds) switches between normal and ad-
dressing mode to adopt the device address from the ETS.
Modem reset button
The modem reset button reinitializes the modem when pressed for
>6 seconds. Then, the central communication unit opens a connec-
tion to the parameterized alarm receivers and delivers a system re-
port.
Button combinations
Press the modem reset and the Konnex bus button simultane-
ously for >6 seconds to retrieve the default state as supplied.
Note: All configuration data and settings will be reset. The device
list and all undelivered messages will be deleted.

Commissioning
Notes
• Operation with a PC: In the case of direct operation with a PC
via RS-232, a standard null modem must always be used be-
tween the 2 devices
• The settings detailed below under "Other settings via the
ACS7... plant operating software" can also be made in advance
Preparations
1. DO NOT switch on power yet.
2. Remove the terminal covers, if fitted.
3. Check wiring to ensure it is in agreement with the plant dia-
gram.
4. For commissioning, RS-232 selector S1 must be in posi-
tion (direct communication with PC via RS-232).
5. For commissioning, signal selector S2 must be in position
(no delivery of messages via RS-232).
6. If required, replace the terminal cover on the mains voltage
side.
7. Switch on power.
Creating the device list
The following choices are available:
• Press the Konnex bus button for at least 6 seconds.
• Make a search run or parameterize with the ACS7... plant op-
erating software, directly via PC and RS-232
• Make a search run or parameterize with the ACS7... plant op-
erating software, via the OCI700 service interface and the
Konnex bus
• Make a search run or parameterize with the ACS7... plant op-
erating software, via modem from the operator station
Notes:
• Creation of the device list with the help of the search run is
recommended only if the number of Synco devices do not ex-
ceed the maximum number of devices that can be connected
to the central communication unit (4, 10 or 64), depending on
the type of central communication unit
• Neither the central communication unit nor the OCI700 service
interface power the bus. To ensure communication, at least
one powering Synco device or one central bus power supply
must always be connected to the bus
• By the time the device search run is completed, the green LED
for operation has extinguished. Then, it flashes 3 times
Other settings via the ACS7... plant operating software
The following settings must be made with the ACS7... plant op-
erating software, via the RS-232 port or via the OCI700 service
interface and the Konnex bus:
