7 System description The OPTILEVEL HLS 6010 probe, OPTILEVEL Supply, T901-P temperature/pressure transmitters and LOG3840 deck digital indicator are parts of the OPTILEVEL system, dedicated to monitor the Barges/Inland vessels liquid cargo parameters such as level, temperature and pressure, as well as all associated measurements. They are installed in hazardous area. The OPTILEVEL HLS 6010 probe measure the liquid level inside the tank and the temperature and transmit the information to the TA3840C communication unit by means of the OPTILEVEL Supply located in Safe area. The T901-P temperature / pressure transmitters measure the liquid cargo temperature (if more than 1 temperature is requested) and the inert gas pressure. Each T901-P transmitter is directly connected to TA3840C analogue input board. (Already Marine certified). The LOG3840 deck digital indicator displays locally the level, temperatures, pressure measured by transmitters. It is powered by the TA3840S safety unit and communicates on a RS485 bus. (Already Marine certified). General synopsis The general synopsis of the system is shown on the previous page. TA3840C, TA3840S, TA3840R T901-P and LOG3840 are part of EMx40 system (see MI5016, MT5016 & MM5016). 2. OPTILEVEL HLS 6010 probe The probe consists of the head housing with the electronics, a screw thread to fasten it to the tank and the measuring tube. The measuring tube varies in length depending on the tank height. Important ordering information: To produce a probe we always need the following information: LL = Tank height LG = Probe length Standard lengths (in mm): Tank height. (LL) Probe length (LG) Segment length Special lengths (minimum/maximum lengths in mm): Tank height. (LL) Probe length (LG) Segment length OPTILEVEL Technical Manual 7

8 3. OPTILEVEL Supply The OPTILEVEL Supply provides the power to the connected probes. Depending on the number of probes to be connected there are different versions available. Up to 4 Supplies can be operated parallely, so that a maximum number of 32 probes can be connected. Superior systems can be connected to the RS232 standard interface. At the same time the Supply takes over the galvanic separation of each individual probe and offers thereby a safe explosion prevention. 4. INSTALLATION 4.1 Potential equalization As the intrinsically safe circuit is operationally earthed, a common potential equalisation must be provided within the intrinsically safe circuit (within and outside the explosion hazardous area). The probe must be connected to the same potential equalisation (earthing) as the tank. See also paragraph: Connect the 4 mm² cable for potential equalisation to the ground clamp on the housing and link it to the tank lid Galvanic separation by OPTILEVEL Supply: The Level Sensor (HLS 6010) is galvanically separated by the ex-barrier (OPTILEVEL Supply). The shield of the connection cable must be connected to the probe head (housing) and to the E terminal clamp on the Supply. Installation regulations: The earthing of the tank, its cables, etc., resides with the installation engineer or the planning office and is normally examined and adjusted on-site. The probe s earthing must also be connected to the tank. OPTILEVEL Technical Manual 8

11 4.4 Laying the cables General Use screened blue polyurethane cable (3x0, 75 mm²) with a diameter of 5 9 mm, which is resistant to oil and petrol products and has a maximum length of 250 meters. THESE CABLES MUST BE LAID SEPARATELY, i.e. they must be isolated from power cables. The valid high voltage current regulations must be observed! CABLE CAPACITY: Please note that the cable capacity together with the probe s inner capacity Ci must not exceed the maximum outer capacity of the Supply (562nF). NEVER LEAVE A CABLE END IN THE LIQUID! Due to the capillary effect the liquid might penetrate the cable and cause a short circuit. 4.5 Installation of the probe Preconditions Procedure All cables are laid A G1½ -inch or NPT female thread has been installed on the dome cover 1. Wind Teflon tape or hemp yarn around the nipple of the compression fitting 2 Untighten the compression fitting gland of the probe (2 x 60mm jaw spanners) are required 3 Slide the compression fitting down to the welding points and tighten it slightly 4 Place the probe in the tank and tighten the nipple 5 Untighten the PVC gland 6 Place the probe on the bottom of the tank 7 Put the sensor adjusting tool on the dome lid and move the slide upwards to the lower edge of the sensor head. Block the slide with the fixing screw 8 Lift the probe slightly and remove the sensor adjusting tool 9 Move the slide of the sensor adjusting tool 10 mm upwards and block it again by means of the fixing screw OPTILEVEL Technical Manual 11

12 10 Place the sensor adjusting tool back on the dome lid in the same position as before 11 Lower the probe until the lower edge of the probe head rests on the slide again 12 Tighten the compression fitting of the HLS (Working thoroughly will ensure that the probe end will be placed exactly 10 mm above the bottom of the tank) To guarantee the density of the installation the compression fitting must be tightened to 70Nm min. Taking a spanner with 500mm length equals a weight of 15 kg! 13 Write down the tank number and medium on the test report (will be needed for commissioning). Mention on the test report if the probe cannot be mounted in parallel to the tank axis OPTILEVEL Technical Manual 12

13 4.5.1 Dimensions LPG gauge (in mm) Electrical connection Laying the cables 1. Connect the 4 mm² cable for potential equalization to the ground clamp on the housing and link it to the tank lid 2. Remove the housing lid of the probe head 3. Untighten the PG gland 4. Skin the probe cable and provide it with cable end sleeves 5. Guide the probe cable through the PG gland 6. Tighten the PG gland until the rubber seal forms a small bulge 7. This cable gland meets the tightness requirements according to IP 66/67, i.e. among others that if the probe is immersed permanently into water, no water may penetrate the electronics. Therefore, this work must be carried out with utmost care! CAUTION! The screening of the probe cable must be provided with an insulating hose. Wire or cable residuals must not remain in the probe head! OPTILEVEL Technical Manual 13

14 4.5.4 Connection of power supply and signals 1 Connect the grounding braid 1 in the housing lid to a free E - terminal clamp on the electronics. 1 2 Connect the probe cable to the terminal clamps on the head electronics The screening of the probe cable is connected directly to the second E - terminal clamp or the additional screw in the head housing! Probe head with grounding braid Electronics with terminal clamps Close probe head housing lid CAUTION! The probe head housing lid must be tightened cross-wisely so that thightness according to ip66/67 is guaranteed. 1. Start by tightening screws 1 and 3 slightly. 2. Then, tighten screws 2 and 4 slightly. 3. Check if the housing lid fits the bottom parallel. 4. Tighten screws 1 and 3 completely. 5. Tighten screws 2 and 4 completely. 6. Note down tank, product and mechanics number (important for probe initialisation). OPTILEVEL Technical Manual 14

15 4.6 Connection of OPTILEVEL Supply Variants Variant 1 (Stand alone) This variant is used if a Supply is used without OPTILEVEL Controller. Variant 2 (Slave) Master and Slave are mounted next to each other (mounting version 1). If there is not enough space Master and Slave can also be mounted above each other (mounting version 2). The OPTILEVEL supply must be mounted outside the ex area! Mounting 1. Open the upper lid of the Supply The picture at the bottom shows a Supply 8. The Supplies 1, 4 and 5 are the same size, but there are less channels assembled. 2. Fasten OPTILEVEL Supply to the wall with 4 screws. ATTENTION! ELECTROSTATICALLY CHARGEABLE COMPONENTS! Reduce electrostatic charge before touching the board. There might be tension on the solder points of the transformers that have not been OPTILEVEL Technical Manual 15

18 5. START-UP Terminal program: You may configure the probe with a terminal program using the corresponding commands. This procedure is described on the following pages 5.1 Preparations General: Requirements: Connect your PC to the Supply via serial interface PC with a Terminal program (e.g. Hyperterminal, OC Console) Connection cable for the serial interface to OPTILEVEL Supply: RS 232 terminal Supply Laptop (9-pole D-Sub) RES Reserve GND GND (Pin 5) RxD TxD (Pin 3) TxD RxD (Pin 2) Make sure that you have the probe mechanics number, the medium as well as the tank number at hand. 5.2 Start Terminal program (Configuration) 1. Start the Terminal program 2. Baud rate: 9600 (standard with delivery) 3. Parity: N (none) 4. Data bits: 8 5. Stop bits: 1 6. Port: depends on the port that is used 7. no handshake 8. local echo on OPTILEVEL Technical Manual 18

19 5.3 Assign address / product (tank) In order to allow the interpreting device to communicate with the single probes, a unique address must be allocated to each probe Commands Entries via Terminal program We recommend you use the tank number as the probe s address, so that each probe can be assigned clearly to a tank. Should you wish to assign different probe and tank numbers, you must create a thorough documentation! Communication with the probes is effected by certain commands. The assignment of probe address and product is carried out by entering the command: *A <probe number> 1. All other commands are described separately in chapter 5. Monitor: Enter the probe s ID number (can be found on type label). In this example it is: A probe address will be requested. Enter a number (two digits). Normally, the tank number is used. The probe will confirm your entry. The probe address is 01. Specify the product which will be in the tank. This entry helps the probe to reach a relatively high accuracy immediately after switch-on and before adjusting itself to the new medium. Remarks: - Enter 4 (Diesel) if the medium is unknown - Enter 8 for products with an Er 2 - value > 3, such as water, AdBlue, E85 The probe will confirm you entry. Done! 1 = <CR> or <Enter> or <Return> 2 Er stands for εr = dielectric constant OPTILEVEL Technical Manual 19
