The PR-OCTO Lean 2G Y8 0T (code no. 300B5070) device is an IoT Enabler speciﬁcally 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.

Electronic thermostats, in general, by monitoring the temperatures and states related to the equipment, control the compressor and fan relays and generate warnings and alarms. By means of a wired connection, PR-OCTO can obtain from the thermostats diagnostic and alarm data relating to the equipment, or create new ones. Thanks to the presence of a modem and an M2M SIM on board, PR-OCTO communicates with the Alsense™ monitoring platform through the mobile network, transmitting the collected data. PR-OCTO also scans the mobile network and nearby WiFi HotSpots to determine its position and transmit it to Alsense™.

If in Alsense™ the refrigeration system is located in a position other than that transmitted by PR-OCTO, an alarm is notiﬁed on the monitoring platform. Authorized personnel can access Alsense™ to view active alarms and decide if PR-OCTO has to lock the operation of the refrigeration system.

Danfoss guarantees a continuous after-sales maintenance of the PR-OCTO devices as they can be updated remotely (FOTA) or on site via the mobile app.

COMM Cable

This distance has to be at least 5 cm in case the power supply is not double insulated

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 oﬀ, 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 Fig 4, 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.

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

The COMM Cable could be either assembled by the cooler manufacturer or could be purchased from Danfoss (see COMM table for details).

5. Choosing the position in the cooler

The most important requirement for the OCTO installation is to ﬁnd the location inside the cooler where the mobile network signal is stronger and the device protected. The diagram below suggests the recommended positions for coolers:

Preferred area:

Inside, On top

Best position:

Inside the canopy

Standard VISI Cooler

Preferred area:

Back, outside,

next to the top

In this case, the OCTO

has to be protected

by an additional cover

in order to avoid any

possible electric shock.

The OCTO has to be unaccessible by any

person.

Lean Cooler

On standard visi coolers the best area is inside the canopy, since the canopy usually does not have metal plates that could decrease the mobile network signal. On lean cooler, since the lack of the canopy and the presence of metallic plates all around the cooler, the OCTO can only be installed outside the cooler, in the back area, next to the top.

Note: In case of installation on the back side of the cooler, the OCTO has to be protected with an additional box to protect people from electric shock.

Mobile application

Danfoss has developed a mobile application for Android and IoS that can be used also for check the best position where to install the OCTO in the cooler. This is the suggested way to check the best position to install the PR-OCTO into the cooler. You can ﬁnd more details at: User Guide for ProsaLink mobile app

PC application

Danfoss has developed a speciﬁc PC software to help discovering the right position of the OCTO in the cooler. To exploit such software, follow these steps:

Step 1: Download the VBCTKSignalTester application from this URL: http://area.riservata.it/

vbctksignaltester-1.0.0-setup-x86_32.exe Step 2: Install the VBCTKSignalTester application in a Windows PC. Step 3: Connect the 'Test Cable' (see Fig. 5) to the PC and to the OCTO. Step 4: Power on the OCTO (see Section 4 for the power supply cable). Step 5: Run VBCTKSignalTester and select the appropriate Serial COM port to which the 'Test Cable' is

connected, as shown in Fig. 6a. Step 6: If the program shows “No Connection” as in Fig. 6b, try to change the COM port listed in the

combo or check the cable connection. Step 7: When the system is ﬁnally connected to the device, it starts to display the Antenna Signal Level

of the OCTO’s internal antenna. Such level could be low (like in Fig. 6e), medium intensity (like

in Fig. 6f) or almost the best signal level (like in Fig. 6d). Step 8: Try to change the position of the OCTO in the cooler in order to discover the highest possible

Antenna Signal Level. Step 9: Power oﬀ the OCTO and disconnect the PC 'test cable'.

Once discovered the best position with respect to the Antenna Signal Level, it is possible to decide if it is the case to protect the Side B (the one with the connectors) of the OCTO. To this aim, it can be adopted the same approach that the cooler manufacturer uses to protect the connector side of the electronic thermostat, hence a piece of plastic with an appropriate shape can be used. If a piece of plastic is not available, a metallic plate can be used but the covered area of the OCTO has to be as small as possible (the limit should be 5 cm from the front of the OCTO, as illustrated in Fig. 7).

5 cm

6. Installation in the coolers During the industrial production of the coolers, there should be a phase in which the electronic thermostat is installed. In the same phase, also the OCTO device has to be installed. The following preconditions have to be satisﬁed:

Pre-condition 1: The installation position has to be determined during the analysis performed as

described in Section 5.

Pre-condition 2: One COMM CABLE for each cooler has been correctly assembled for the

corresponding thermostat model with the appropriate length with respect to the position of both the OCTO and the electronic thermostat.

Pre-condition 3: A power supply cable has been prepared using one of the connectors illustrated in

Fig. 4.

Pre-condition 4: If a metal protection is provided, this must not cover the antenna of the device (see

Fig. 7).

Pre-condition 5: the controller has to be programmed in order to properly manage all the sensors.

Thus, for example, if a door sensor is installed, even if it is not needed for the cooler management (i.e. no need to switch oﬀ the fan), the controller must be programmed in order to properly detect and manage the door sensor itself. For any clariﬁcation, ask to your local Danfoss agent.

For the installation, the following steps have to be performed:

Step 1: While the cooler is oﬀ, put the OCTO unplugged inside the cooler in the appropriate position. Step 2: Connect the COMM cable to the thermostat and to the OCTO. Step 3: Connect the power supply cable to the OCTO while such cable is not powered, as illustrated in

Fig. 3. Step 4: Install the protection, if any. Step 5: Power on the cooler (and consequently the OCTO). The red led of the OCTO starts blinking.

Wait until the red led stops blinking. If it results always on, then the device is powered and the

communication with the electronic thermostat is correctly established. Step 6: Wait until the green led remains always on. Step 7: In case of success in STEP 6, and only in such case, the cooler code and the OCTO code have

to be associated. This association is illustrated in Fig. 8. Both the cooler serial number and

the OCTO Device Code have to be read using a bar code reader and to be traced in a special

document where the cooler model, the cooler serial number and the OCTO device code must

be written.

Note: In case STEP 7 is not properly executed, the future owner of the cooler will not recognize the cooler through the Prosa infrastructure.
