Monitoring unit Type PR-OCTO

IoT Enabler for remote control and tracking of refrigeration equipment

The PR-OCTO device is an IoT Enabler specically designed for cooling applications like bottle coolers, ice cream cabinets and other refrigeration type of equipment. This Enabler allows connectivity and access to the Alsense™ Cloud solutions from Danfoss.

The OCTO can operate connected to existing electronic controllers, gathering the data from the controller using a communication port or as a stand alone device, using the 4 available inputs to gather temperature and status information. Using the embedded modem, the Bluetooth link and the WiFi capabilities of the device, it can provide multiple options of communications with the cloud and very accurate positioning.

Compatibility

The PR-OCTO device gives the possibility to execute the lock command and to collect the diagnostic information only in conjunction with an electronic thermostat.

The current version of the PR-OCTO includes the compatibility with the thermostats listed in Table 2.

Table 2: Compatible electronic thermostats

List of compatible controllers is updated frequently, please consult your Danfoss representative for controllers not included.

Connections with an electronic controller

Figure 3: Connection to an electronic controller

The PR-OCTO requires two connections, one for the power supply, the other with the electronic thermostat.

The power supply must be shared with the electronic thermostat: the PR-OCTO must be powered on only when the thermostat is also powered on. If the PR-OCTO is powered on when the thermostat is o, a “Controller communication failure” alarm is raised after 60 minutes.



NOTE:

Neither the cables nor the connectors are included in the PR-OCTO package.

For the POWER SUPPLY connector of the PR-OCTO, either two standard fast-on connectors or one connector with screw terminal can be used. In Table 3, illustrates the Lumberg 3611 02 K1, an easy plug connector with lift clamp and protection against misplacing and fast assembling. Neither the easy plug connector nor the standard fast-on connectors are included in the PR-OCTO package.



NOTE:

If the power supply cable is not double insulated, it must be physically separated from the COMM cable.

Monitoring unit, type PR-OCTO

Concerning the COMM Cable (the communication cable between the PR-OCTO and the electronic thermostat) a specied cable must be used depending on the specied thermostat.

The COMM Cable could be either assembled by the cooler manufacturer or could be purchased from Danfoss.

The PR-OCTO is compatible with the following Danfoss controllers: ERC11X (models ERC112 and ERC111), and EETa (models EETa 2W, and EETa 3W). Table 7 shows ordering codes for the communication cable between Danfoss controllers and PR-OCTO.

Connector pinout

The pinout of the COMM connector (see Figure 4) is the following:

• Pin 1: +5V out (max 150 mA)

• Pin 2: TTL port 2 Rx (input to PR-OCTO, Tx output from Controller), CAN H on 300B5074 model

• Pin 3: TTL port 2 Tx (output from PR-OCTO, Rx input to Controller), CAN L on 300B5074 model

• Pin 4: TTL port 1 Tx (output from PR-OCTO, Rx input to Controller)

• Pin 5: TTL port 1 Rx (input to PR-OCTO, Tx out from Controller)

• Pin 6: Ground

NOTE:

This functionality is not available on the 300B7073 model and it is partially available on 300B5074 model. Each input can be used to connect a NTC sensor or a voltage free switch. In the following, some examples of possible installations. After the electrical connection, the PR-OCTO must be congured properly.

The suggested conguration is:

• NTC1 to monitor cabinet temperature

• NTC2 on evaporator

• Switch 3 on Door 1

• Switch 4 on Door 2

The NTC sensor can be a Danfoss type EKS 221 or one with the same characteristics (i.e., 10 kΩ at 25 °C and Beta 3435 at 25/85 °C).

Installation with a RS485 or RS232 electronic controller

In case the controller has an RS485 or an RS232 communication, the Optional connector can be used.

The mating connector is JST PHR-4 (see Figure 9) and the following wiring must be followed:

• Pin 1: 5 V power out (max. 150 mA) do not connect

• Pin 2: RS485+ or RS232 Tx (output from PR-OCTO, Rx input to controller)

• Pin 3: RS485- or RS232 Rx (input to PR-OCTO, Tx output from controller)

• Pin 4: Ground

Warnings

WARNING:



• The installation of the PR-OCTO has to be performed only and exclusively by qualied and skilled technicians.

• The installation of the PR-OCTO should be performed while the cooler is switched-o.

• Inside the device there is a GPRS antenna. For this reason, while the PR-OCTO is working it must be at the minimum distance of 9.5 cm (4”) from the people. The installation must be done to ensure this distance.

• The PR-OCTO has to be installed in a protected position. The PR-OCTO has to be embedded in the cooler and not accessible. In case of installation on the back side of the cooler, the PR-OCTO has to be protected with an additional box to protect people from electric shock.

• If the power supply cable of the PR-OCTO is not double insulated, it has to be physically separated from the COMM cable (the communication cable with the thermostat).

• The PR-OCTO input power supply is protected by over-currents by the F002 device, with this characteristics: delayed fuse 250 V 400 mA.

• Any document related to the conformity declaration of the PR-OCTO can be downloaded from www.danfoss.com.

• This equipment is not suitable for use in locations where children are likely to be present.
