Connection Of Accessories - Nice MC200 Instrucciones Y Advertencias Para La Instalación Y El Uso

4.4 - Connection of accessories

To connect the relevant accessories refer to Table B, to Fig. 3 and to the instruction manual of each accessory. Table B summarises all the ac-
cessories that can be connected to the control unit terminals and the specifications for making the electrical connections. Before proceeding,
carefully read the table and its notes. Note – Due to the fact that certain inputs offer different functions for connecting the accessories, once the
connections have been made it will be necessary to set the dip-switches according to the accessories connected (see Chapter 5 - Programming).
Table B - Function of the terminals (inputs and outputs)
Terminals Description of the function
1 - 2 Output for flashing warning light at the mains voltage.
3 - 4 - 5 Output for controlling the motor (open, common, close).
6 - 7 Input of the power supply line coming from the mains (live, neutral).
8 Reference to 0 V for the "Common" conductor of the devices connected to terminals 9, 10, 11, 12 and 13.
9 24 V output. Output for devices (for example, photocells) with 24 V
10 Photo test output. 24 V
11 Stop input. Input for safety devices with 8.2 kΩ fixed resistor (sensitive edge, etc.).
12 SbS input. Input for a normally open (NO) button, for sending commands in step-by-step mode.
13 Photo input. Input for a normally closed (NC) reception photocell (RX), or for a normally open (NO) button.
14 - 15 Input for an antenna-radio receiver.
4.5 - How to manage the "Photo test" output and the "Stop", "SbS" and "Photo" inputs
4.5.1 - Photo test output (terminal 10)
This output must be configured through programming dip-switch 7 depending on the type of device connected: if a transmission photocell (TX)
is connected, the dip-switch must be set to ON; if instead a "door open indicator light" is connected, the dip-switch must be set to OFF.
NOTES • If a "door open indicator light" is connected to this output, the TX photocell must be connected to terminal 9. • The "door open indica-
tor light" signals have the following meanings:
light off = door closed; light on = door open; slow flashing = door in opening phase; fast flashing = door in closing phase.
4.5.2 - Stop input (terminal 11)
This input must be configured through programming dip-switches 1 - 2 depending on the type of device connected: normally closed (NC) con-
tacts, normally open (NO) contacts or fixed resistance (8.2 kΩ) contacts. Warning! - Only the use of a fixed resistance contact together with
the OFF+OFF setting of dip-switches 1 - 2 guarantees the minimum level of resistance against faults, requested by the regulations. Normally the
output for a transmission photocell (TX) or for a "door open indicator light" function. Maximum current draw: 50 mA.
power supply (low-voltage): maximum current draw: 100 mA.
