Electrical Installation:

Power Connections:

• 12VDC Input: Connect to power source
• 12VDC Output: Use + and – terminals for output

Relay Connections:
Ensure max load restrictions (2A-30VDC) are adhered to. Use a varistor for inductive loads.

Inputs:
Identify and connect bridge cables based on input configuration.

Online/Offline Configuration:
Use the jumper to configure the unit for offline operation.

Dip Switch Settings:

• Offline Mode: Assign output numbers to relays based on the provided table.
• Tamper Input: Connect tamper signal from external devices.

FAQ:

• Q: What is the maximum power consumption of the CU4EB8?
  A: The maximum consumption is 1.5A when using the output power port. If not using the output port, the maximum consumption is 500mA.

• Q: What type of cable is recommended for BUS485 Inputs?
  A: Twisted pair cable with AWG24 specification is recommended for BUS485 Inputs.

• Q: What is the rated load for the output relays?
  A: The output relays support a rated load of 2A-30Vdc.

Dimension

The CU4EB8 expansion board unit provides multi-relay switchable output management to external systems such as lift floor level access, multi-shutter and barrier systems, machine switching and more.

Installation guide

Mechanical Installation

• CU4EB8T – CU4EB8G

Note:
Follow the same connection model, using the CU tamper input, when using a third-party electric box equipped with a tamper opening detection.

Note: To override the wall tamper, place the jumper in the OFF position.

1. Physical tamper switch to be operated by external electric box models.
2. BUS RS485 Terminal Resistor must be in the ON position when the CU is connected at the end of the BUS.
3. Power Input.
4. Power Output: This output is directly connected to the power input port protected by a 1A fuse.
5. BUS485.
6. Relay Connections: Please take into account the max. load restrictions(2A-30VDC). Use the provided varistor if an inductive load is used.
7. Inputs: The Installer must identify the bridge cable needed depending on the input configuration.
8. Online/Offline jumper: Configure the unit to work as an offline device. Dip switch:
9. Offline Mode->See the output table to assign the output number to a relay.
10. Tamper input to connect the tamper signal from the SALTO electric box or other compatible devices.

Output relays

Rated load(resistive) 2A-30Vdc

• Note 1: This is the maximum consumption of the CU4EB8 using the output power port (1A max). If the power output port is not used, the maximum consumption is 500mA
• Note 2: Same voltage as the input.
• Note 3: 1K pull-up resistor.
• Note 4: See the software User Manual.

Installation example:

Offline configuration

1. The unit must be connected to a CU4200 in stand-alone mode (dip-switch in the CU4200 -> 0000).
2. In offline mode, the inputs are disabled.
3. The dip-switch configures the number of the output in the different relays as the following table.
4. To assign the output number to a specific user see SALTO ProAccess SPACE User Manual.

TABLE 1

Online Configuration

1. Connect all the devices through the BUS485 and power the CU4EB8.
2. Create and set up the CU4EB8 on the Software (Consult the SALTO ProAccess SPACE user manual).
   • Asign the CU4EB8 to the node it is connected.
   • Define the address in the BUS485.
   • The relay-out set-up has to be done through the SALTO ProAccess SPACE software.
3. Put the Resistor in ONLINE mode.
   • The CU4EB8 dip-switch setting is used to give each device on the BUS485 a unique address.
   • Ensure that the address in the software is the same as the one you put on the hardware. (See Table 2).
   • Both ends of the BUS485 must have the RS485BUS termination resistor in the ON position, intermediate devices need to have the resistor in the OFF position.

Supervised input connections:
By default all inputs are disabled. They can be configured through the software. If the inputs are supervised, the resistance values R1 and R2 are defined in the software: 1k (recommended), 1k5,2k2,3k3,4k7,6k8,10k.

Signalling:
The LEDs in the top layer of the CU4EB8 show the state of the system:

| LED name|

Description

---|---|---

ON

| GREEN ON: the unit is powered correctly
BLINKING RED: the unit is not powered properly (check power supply)
OFF: not powered
TAMPER| ON: tamper alarm active
OFF: tamper alarm not active
IN1-IN4| ON: active input (depends on the input type configured in the software)
OFF: inactive input (depends on the input type configured in the software)
RL1-RL8| ON: the relay is activated (NO is connected with C).
OFF: the relay is inactive (NC is connected with C).
