Installation & User Manual Ed 19UK June 2013 Type MAS2600-XXX-XX-X/XX A: Absolute Transducer. The absolute transducer has no breather pipe, because it refers to absolute vacuum. An atmospheric pressure sensor is used to compensate for the atmospheric pressure. The absolute transducer is especially suitable for open deck applications, where the amplifier box may be exposed to flooding. G: Gauge Transducer.
Installation & User Manual June 2013 Ed 19UK Absolute Transmitter: The MAS2600 Absolute Transmitter is available in two ranges. The output signals are calibrated as follows: Transducer type 4 Transducer type 7 : 0.8 - 3.5 bar abs : 0.8 - 2.0 bar abs Selecting the Measuring Range: When selecting the measuring range it is important to consider the tank height, vent pipe height, the tank type and the specific gravity (SG) of the tank contents.
Installation & User Manual Ed 19UK June 2013 Absolute Transducers: The Absolute Transmitter is typically used if the amplifier is exposed to water, e.g. on open deck. The Absolute Transmitter is available in 2 ranges: 0-20 and 0-35 mH2O. In practice this means 10 mH2O less than the nominal range because of the atmospheric pressure which must be taken into consideration when choosing the transducer. A transducer with an effective range larger than the tank height should be selected. Basic Rules: 1.

Installation & User Manual Ed 19UK June 2013 Amplifier Box MAS2600-XXX-XX-X/XX The MAS2600 amplifier box is manufactured in polyester, which has the strength and stability of aluminium, insulation and resistance properties of plastics. Colour code RAL 7000. The amplifier box is protected to the level of IP 56 and must be mounted outside the tank, e.g. in the engine room or other dry areas. The amplifier box is available with a PG9 hole for silicone gel filling to protect the amplifier from moisture.
Installation & User Manual June 2013 Amplifier PCB Ed 19UK MAS2600-XXX-XX-X/XX The PCB is available in different types for the different transducers, with or without terminals for Pt100 temperature sensor. 0: Without amplifier PCB. P or S: Programmable output range. The amplifier can be calibrated to 4-20 mA output in whatever range wanted within the transducer range. Calibration is made by means of dip switches and potentiometers. D or M: Differential output range.
Installation & User Manual Ed 19UK June 2013 Handling The MAS2600 transducer is a highly sensitive electronic piece of equipment and proper handling is most important. To avoid damaging the transducers: • NEVER lift by the cable if transducer is mounted with fittings. • NEVER remove the protection cap in front of the diaphragm before installation. • NEVER knock the transducer. • NEVER apply pressure to the diaphragm in any way whatsoever, whether using fingers, tools or sharp objects.
Installation & User Manual June 2013 Ed 19UK Installation Prior to installation please check that: • the serial numbers on the transducer, amplifier and lid of amplifier box agree. The serial numbers are to be found on the inside of the lid of the amplifier box on the bottom line amplifier S/N and transducer S/N on the range label. • the transducer is fitted in the correct tank. • the transducer is correctly connected to the amplifier.
Installation & User Manual Ed 19UK June 2013 If the amplifier box is installed in an area with over pressure or negative pressure in relation to the atmospheric pressure in the tank, the breather tube must be directed to an area with atmospheric pressure equalling the pressure inside the tank. This applies to gauge transmitters only. For absolute transmitters this has no affect, due to the reference to absolute vacuum and not atmospheric pressure. This is also the reason why no breather tube is necessary.
Installation & User Manual June 2013 Ed 19UK Intrinsically Safe Installation The MAS2600 is designed for use in an approved intrinsically safe installation. The amplifier is fitted with a label describing the IS category: S/N: XXXXXX-YYYY DEMKO 11 ATEX 146506X IECEx ULD 10.0013X Ui: 29V Ii: 93 mA Li: 20µH Ci: 60 nF Pi: 0.68 W II 2(1) G Ex ia IIC T4 Tamb.: -20 to +80 °C Damcos A/S, Aaderupvej 41,DK-4700, Naestved Where S/N : serial number – production year.
Installation & User Manual Ed 19UK June 2013 Before installing intrinsically safe units within an approved installation, it is essential to ensure that there are no deviations from the conditions of the order or the requirements of the approved block schematic diagram and the following related instructions: 1. No circuits other than those shown on the drawing are permitted. There must be no interconnection to any other circuits. 2.

Installation & User Manual Ed 19UK June 2013 Testing and Recalibrating Please observe that testing and recalibration of sensors mounted in hazardous arias shall be carried out of Ex qualified personnel. Testing Before dispatch, the MAS2600 transmitter is calibrated in accordance with the requirements specified in the order. The transducer and the amplifier are calibrated together and must, therefore, always be used together.
Installation & User Manual June 2013 Ed 19UK Recalibrating Gauge Transmitter using Vacuum (for gauge transmitters only) An internally mounted transducer can also be recalibrated by using vacuum. 1. Check that the tank is empty. 2. Check that the range select switch on the amplifier is correctly set. 3. Set the calibrator to vacuum mode. 4. Connect the hose from the calibrator to the breather tube from the transducer cable. 5. In conditions of no pressure the output signal should be adjusted to 4.
Installation & User Manual Ed 19UK June 2013 Recalibrating the Absolute Transmitter using Test Cup type G022S100 When recalibrating the MAS2600 Absolute Transmitter a pressure calibrator with a range of -1 to 3.5 bar should be used. It should have an accuracy of 0.05% FS or better, as well as a 4½ digit milliampmeter. If a calibrator without reference transmitter is used, the atmospheric pressure must be known to calculate the correction.
Installation & User Manual June 2013 Ed 19UK EXAMPLE: If the range of the transducer is 3.5 bar abs and the atmospheric pressure is 1005 mbar. Calculated output at atmospheric pressure: mA @ Atm.press = 4 + 16 * (1005 − 800) = 5.215 mA 3500 − 800 Calculated applied pressure for maximum output: mbarg @ 20 mA = 3500 − 1005 = 2495 mbarg Calculated pressure at 50% of the transducer range: mA @ P mbarg = 4 + 16 *(1005 − 800 + 1750) = 15.
Installation & User Manual Ed 19UK June 2013 Maintenance and Trouble Shooting Maintenance Damcos recommends that the following to be checked annually: 1. Visual inspection of the cable, transducer and amplifier. 2. Compare signal with e.g. hand sounding, and if necessary perform a zero and full-scale calibration. Trouble Shooting If the MAS2600 transmitter is not functioning in accordance with Emerson Process Management Marine Solutions, Damcos instructions, check that: 1.
