Cautions or Warnings

⚠️ This controller is an Electro-statically sensitive device. Proper ESD protection (ground strap) should be used when installing this product so that damage to the product does not occur.

Danger of explosion if the battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions. Replace the battery with type CR2032.

Equipment damage or loss of data may occur if these procedures are not followed as specified.

Installations requiring CE conformance: All wiring for CE rated products must use an extra low voltage (SELV) or protective extra low voltage (PELV) transformer. Use safety-isolating transformers, (Class II transformer) per EN61558. The transformer must be rated for 100% duty cycle.

Mounting

The DSC-1616 includes a plastic enclosure that can be quickly mounted with two screws (not provided). This controller should be mounted in an appropriate location within packaged equipment or another enclosure that meets code requirements.

Controller Configuration

Controller Type

Various products have the capability of being configured as one of several possible controller types, which represents the network level that it will reside on in the network architecture (Area, System, Subnet). Other than the one controller acting as a router, all other controllers on the same network segment must be configured the same.

• Area - Configures the controller as an Area level controller on a network. This is an option only on the Ethernet model and is the setting when the controller is connected to an Ethernet network (typically between buildings) and is acting as a router from one LAN to either a network of System controllers or Subnet controllers.
• System - Configures the controller as a System level controller on a network of System controllers. This is the setting when the controller is connected to an Ethernet or BACnet MS/TP network with other System controllers or is a single head-end controller for a network of Subnet controllers.
• Subnet - Configures the controller as a Subnet level controller on a Subnet of similar controllers. This is the setting when the controller is connected to a BACnet MS/TP network with other Subnet controllers.

Note: This also determines where the DIP or MAC address is mapped into the controllers BACnet address and which other portions of its BACnet address are inherited when DNA is enabled.

Diagram: Visual representation of Area, System, and Subnet settings.

Derived Network Addressing

The DNA jumper comes ON by default. This allows the controller to automatically configure a BACnet controller address. This should NOT be removed unless you are assigning a BACnet controller number through software. The BACnet controller number should not be confused with the DIP switch setting, and each controller must still have a unique dip switch address even when using software to define the controller number.

Diagram: Visual representation of the DNA jumper setting.

Controller Addressing

The Dip Switch is a binary switch. Each individual DIP switch represents a unique value, which forms the controller address when added together.

To set the address, simply move the switches that add up to the controllers desired address to the ON position.

Example: If the controller is to be address 5 on the network, set the switch numbered 4 and the switch numbered 1 (equals 5) to the On position.

Note: Each controller on the same MS/TP segment must have a unique DIP switch address.

Diagram: A visual representation of DIP switches labeled 1 through 8, with an ON/OFF indicator.

Wiring General

All wiring must conform to NEC and local codes and regulations. Use earth ground isolating step-down Class 2 transformers. Do not use autotransformers. Determine supply transformer rating by summing total VA of product and output loads.

⚠️ More than one disconnect switch may be required to de-energize the equipment before servicing.

ℹ️ Input Class 2 Power Supplies are interconnected. Use only Class 2 sources suitable for interconnections.

• All terminals are acceptable for Class 2 Circuit connections only
• Use copper conductors only
• Apply minimum 6.0 lb-in torque for tightening field wires into the terminal blocks

Power

This product is designed to use a 24 VAC, Class 2 power supply. The proper specified cabling must be used. (18 – 16 AWG, 2-conductor wire)

A single transformer may be used to power multiple controllers and/or auxiliary field devices (actuators, etc.) provided the following conditions are met:

• All devices MUST be 1½ wave rectified. Mixing power between 1½ wave and full wave rectified devices will damage both the transformer and connected equipment.
• The transformer is properly sized, including line losses for the total VA requirements.
• Polarity is observed between controllers (with respect to 24~ and Gnd).
• Each controller is grounded as shown in the diagram below. This is important to protect equipment and ensure a common ground reference for RS-485 communications.
• The transformer secondary is fused for its maximum rated load (4A max for Class 2 circuits).

Diagram: A wiring diagram showing a 24VAC (Class 2) transformer powering two devices. It illustrates the grounding connections for Device 1 and Device 2, including the use of a ground lug and a terminal labeled GND.

ℹ️ Make sure to ground the controller using the ground lug that is available on the controller.

Network Communication

The controller communicates on Twisted Pair Ethernet 10-BaseT using BACnet IP and BACnet over Ethernet, or on an RS-485 LAN using the BACnet MS/TP protocol. Refer to Delta Controls Wiring Guidelines for further details.

MS/TP (RS-485) Wiring

For detailed information on MS/TP and LINKnet wiring refer to Delta Controls Wiring Guidelines.

• The proper specified cabling must be used to ensure reliable communications. (22 AWG twisted pair, 100-120 ohms impedance, 17 pF/ft or lower capacitance, with a braided or aluminum foil shield.)
• Controllers should always be wired together in a daisy-chain fashion. Attempting to connect them using a starred or bus configuration will cause problems on the network.
• Networks with a total length greater than 4000 ft or with more than 50 controllers require a repeater (RPT-768).
• LINKnet networks that have only 1-2 controllers, and have less then 100 ft of cable length do not require network terminators.

Diagram: A schematic illustrating RS-485 daisy-chain wiring with shield connections and network terminators.

Input and Output Wiring

Inputs and outputs on the DSC-1616 controller follow the same general wiring requirements as other Delta Controls products. Recommended cable types should be used as listed below. Refer to the Delta Controls Wiring Guidelines for more details.

Input Configuration

The input must be configured to accept the signal used by the input device. Place the jumper for each input in the correct location on the Input Type Selector Block. The diagram to the right shows the factory default selection of 10 KΩ.

• 4-20mA - For sensors that use a 4 to 20 mA signal.
• 10K - For 10 KΩ Thermistor temperature sensors, as well as Dry Contact binary inputs.
• 5V - For sensors that use a 0 - 5 VDC signal.
• 10V - For sensors that use a 0 -10 VDC signal.

Diagram: A visual representation of input type selector options: 4-20mA, 10k, 0-5V, 0-10V.

Output Configuration

Each HOA switch is HAND, OFF, AUTO from right to left. The HAND position allows a user to manually force the output on, the OFF position allows a user to manually force an output off, and the AUTO position allows the output to be controlled automatically by the controller.

Diagram: A visual representation of the HOA switch positions.
