SC441C7xx Series User Manual ML000044 © 2009 All Rights Reserved Page 5 1 PRODUCT DESCRIPTION The SC441 Transmitter Series is specifically designed to be mounted on gas tanks and connect to existing tank float gauges and gas meters, eliminating the need for expensive intrinsic safety barriers and wiring to the tank or meter. Each site must have a dialer and the SC441 periodically communicates with the site dialer using low power radio transmissions in the ISM band, and the dialer then transfers the collected tank levels and gas usage data to the GASLOG Server. SC441 transmitters are typically used on a GASLOG telemetry site where: • there are more appliances than can be directly connected to the site dialer, • the appliances are physically separated from one another, and/or • the dialer must be located away from the appliances in order to get adequate GSM coverage or connect to the PSTN fixed telephone network. The SC441 is powered by an internal lithium battery and under normal operating conditions will give many years of operation on the original battery. To achieve this, the SC441 is normally in a powered down state and only wakes up for short periods to take measurements and to communicate with the site dialer. Figure 1 : GASLOG Telemetry Site
SC441C7xx Series User Manual ML000044 © 2009 All Rights Reserved Page 6 1.1 Connectors On the underside of the SC441 transmitter there are 2 connectors labelled A and B. A variety of Silicon Controls sensors and senders can be inserted into these connectors including SC645 tank level senders. Figure 2 : SC645 Tank Level Sender
SC441C7xx Series User Manual ML000044 © 2009 All Rights Reserved Page 7 2 INSTALLATION 2.1 Positioning the Transmitter The prime consideration when positioning the SC441 is the radio performance. The main factors that affect the performance of radio communications between the dialer and the transmitter are the transmission distance and the presence of obstacles in the path between them. Ideally there should be a direct line of sight between the dialer to the transmitter. However this is sometimes not achievable. Obstacles that can affect performance include items such as vehicles, garages, trees, posts, brick walls etc. Choose a position for the SC441 where you can conveniently make the cable connections to the monitored appliances and that is not close to pipes, metalwork or other obstacles. If you are monitoring a gas tank, then the best position is generally on top of the tank. Place the transmitter in the chosen position but DO NOT glue it into position at this stage. NOTES: • The SC441 should preferably be mounted horizontally on a surface wider than 0.4m (such as the top of the tank). • The SC441 should not be positioned closer than 0.5 meter from a SC414 dialer. At such short range radio performance may be unreliable or not work at all. • The SC441 contains a radio antenna which should not be covered or obstructed by any metallic objects – doing so may significantly reduce the effective radio range. Figure 3 : Ideal position for a SC441 on a horizontal tank 2.2 Installing Sensors and Cabling During this step, the connections are made from the appliances being monitored and the SC441 transmitter. Detach the bracket of the transmitter, connect the Sender and reattach the base.
SC441C7xx Series User Manual ML000044 © 2009 All Rights Reserved Page 8 Securing the Transmitter 2.2.1 Fixing the Transmitter to a Horizontal Tank • Clean the relevant section of the tank with primer. • Lay out the cable so that there is no slack - excess cable should be neatly coiled and not dangling. • Turn the transmitter upside down and apply a 3mm bead of adhesive around its base. • Fix transmitter to the tank in the location and direction determined during testing. • Once fixed in position the transmitter must not be moved. NOTE Do not disturb the Transmitter once in position, this will allow the adhesive to cure and secure the Transmitter to the tank. In adverse weather conditions the adhesive may take up to 48 hours to cure. Figure 4 : Applying adhesive to transmitter base Figure 5 : SC441 on a horizontal tank

Insert the tool as shown below and lever the Transmitter away from the grey mounting plate. Then turn the Transmitter upside down and carefully remove the Sender cable. Clean any debris off the mounting plate, insert the Sender cable into the Transmitter, place the new Transmitter into position and lever back until it locks. 3.2 Maintaining the Transmitter The Transmitter is powered by a primary battery and has no user serviceable parts. The following should be inspected every time the tank is filled: • Housing is clean and has no cracks or significant abrasions • Mounting plate is securely fastened to the tank • Outer sheath of the Sender cable is not damaged • Sender is properly in place HAZARD WARNING: • Use a damp cloth to clean the Transmitter housing to avoid static discharge.
