CHANGE HISTORY

1. OVERVIEW

1.1. SYSTEM

The SC415 Cellular Dialer is part of a telemetry system designed to provide continuous monitoring of gas tank installations. Tank level and other status information is transferred from the remote site to the enterprise database according to a defined reporting schedule.

Sites communicate with a server using the mobile telephone network (LTE Cat-M1). The server stores the site information in an industry standard SQL database that can easily be integrated into other processes in the supply chain.

1.2. SITE EQUIPMENT

Each cellular telemetry site consists of two primary components:

• SC415 Cellular Dialer - Connects to sensor(s) and performs data logging and Server communications via a cellular network.

• Sensor(s) - Senders are attached to the float gauge and provide locally wired tank level information for the SC415 Cellular Dialer.

2. SC415 CELLULAR DIALER INSTALLATION

NOTE: This product should only be installed by qualified personnel.

2.1. OVERVIEW

The SC415 Cellular Dialer is specifically designed to mount on LP-Gas tanks and monitor existing tank float gauges via a Sender, eliminating the need for expensive intrinsic safety barriers and wiring. The SC415 communicates daily with the server via a cellular network, transferring all the recorded tank level data to the server.

2.2. LOCATION

The location of the Dialer is a prime consideration.

• Not close to pipes, metal-work or other solid obstacles (other than the body of the tank upon which it is mounted).

• As high off the ground as possible.

The location should minimise the chance of the Dialer being subject to physical shock or vibration.

NOTE: The cellular network signal strength is often improved by mounting the Dialer higher or further away from metal objects.

2.3. INSTALLING A DIALER AND SENDER ON A TANK

A range of mounting options are available for common installation situations. Detailed pictorial instruction sequences for these mounting options are provided in the following documents:

Only the most common options are listed in this table. Contact Anova for assistance with other mounting scenarios.

2.4. COMMISSIONING

To Commission the SC415, a Service call needs to be made to initiate a connection to the server. This is done by Activating the dialer as shown in Figure 1. When the magnetic Activation Tool is sensed by the SC415 the red LED will illuminate. Refer to APPENDIX A for details of the activation sequence(s).

Figure 1 - SC415 Activation

A Service call activation initiates a connection to a server using the cellular network. The LEDs will indicate the status of the connection process which could take a minute or two. If the connection is successful the SC415 will retrieve its operational parameters from the server.

The outcome of Service Call is shown for 5 seconds before the SC415 returns to sleep state. The green LED remaining on for 5 seconds indicates that the Dialer has made a successful connection, has been configured and is now in operational state. The red LED remaining on for 5 seconds indicates either a connection or configuration problem.

3. SC415 OPERATION

3.1. OVERVIEW

The SC415 provides two field connectors for connecting Senders. In most applications only one of these will be used, preferably the A connector. The SC415 incorporates a Real Time Clock (RTC) to schedule sampling and regular reporting. It communicates with a server using a packet data service (TCP socket) on the cellular network.

The SC415 takes a level data sample from the Senders every 30 minutes and records temperature data at the time of making a call. This data is delivered daily to a server at a configured reporting time and this connection is referred to as a "Reporting" call.

The SC415 has 3 states: Transport; Operational; and Decommissioned. During production, the SC415 is placed into Transport state. In Transport state, the SC415 remains in its sleep state and will not sample or make Reporting calls.

In Operational state, the SC415 collects sample data and makes daily Reporting calls.

In Decommissioned state, the SC415 makes a Reporting call on the first day of the month, but does not take samples or make daily Reporting calls.

A user can initiate a call to the server by manually activating the device. This is referred to as a Service call.

3.2. INSTALLATION

During installation, the installer must initiate a Service call to connect to the server. See APPENDIX A for detailed activation sequence. On a successful connection to the server, the SC415 will receive its configuration, its reporting call time will be set and it will return any initial sample values to the server.

The SC415 will typically change state from Transport or Decommissioned to Operational state during this connection.

A service call can also be made by a service technician or delivery driver after the SC415 has been Commissioned. This allows configuration changes to be made and any stored data to return to the server.

3.3. NORMAL OPERATION

Once the SC415 is in Operational state, it will make daily Reporting calls at the configured reporting call time.

The SC415 will make up to 3 attempts to connect to the server. If all three attempts are unsuccessful, the SC415 return to its sleep state. Another reporting call will be initiated at the reporting time on the following day. During the Reporting call, sample history, temperature data and current sensor values are delivered to the server. 

3.4. SAMPLING

The SC415 samples each enabled Sender channel every 30 minutes on the hour and 1/2 hour. Temperature is sampled at the time of making the call.

The SC415 has sufficient memory to hold 7 days of sample history. This prevents loss of sample data in situations where the SC415 fails to connect to the server at its regular Reporting call time. If the SC415 fails to connect on 7 consecutive days, the oldest sample data will be overwritten with new sample data and the older data will be lost.

3.5. DECOMMISSIONING

When the SC415 is being removed from a site, it should be Decommissioned. In Decommissioned state, the SC415 stops sampling and making daily Reporting calls.

The device can only be decommissioned by the server setting it into Decommissioned state. This can occur either during a Service call or a regular Reporting call.

4. APPENDIX A - SC415 ACTIVATION SEQUENCE

The following table describes the SC415 user interface. Holding the SC664A activation tool adjacent to the LEDs  causes the SC415 to exit its sleep mode. The period that the activation tool is held adjacent to the LEDs determines the modes that the SC415 enters. Less than 4 seconds provides a battery status, between 4 and 9 seconds initiates a service call and more than 10 seconds enters test mode.

The LED sequences provide status and result indications for each mode.

Table 1: SC415 Activation Sequence

 * To make a service call, activate the Dialer by holding the activation tool next to the LEDs until the green LED starts flashing (5-6 seconds), then remove activation tool.

 ** GPS fix only occurs the first time the Dialer is activated within any 15-minute period.
