WARNING Calls attention to a procedure, practice, or condition that could cause bodily injury or death. CAUTION Calls attention to a procedure, practice, or condition that could possibly cause damage to equipment or permanent loss of data. WARNINGS The following general safety precautions must be observed during all phases of operation, service, and repair of this product. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture, and intended use of the product. DEWETRON Elektronische Messgeraete Ges.m.b.H. assumes no liability for the customer’s failure to comply with these requirements. All accessories shown in this document are available as option and will not be shipped as standard parts. 6 Safety instructions Safety instructions for all DEWETRON systems The DEWETRON data acquisition systems may only be installed by experts. Read your manual before operating the system. Observe local laws when using the instrument. Ground the equipment: For Safety Class 1 equipment (equipment having a protective earth terminal), a non interruptible safety earth ground must be provided from the mains power source to the product input wiring terminals or supplied power cable. DO NOT operate the product in an explosive atmosphere or in the presence of flammable gases or fumes. DO NOT operate damaged equipment: Whenever it is possible that the safety protection features built into this product have been impaired, either through physical damage, excessive moisture, or any other reason, REMOVE POWER and do not use the product until safe operation can be verified by service-trained personnel. If necessary, return the product to a DEWETRON sales and service office for service and repair to ensure that safety features are maintained. Keep away from live circuits: Operating personnel must not remove equipment covers or shields. Procedures involving the removal of covers or shields are for use by service-trained personnel only. Under certain conditions, dangerous voltages may exist even with the equipment switched off. To avoid dangerous electrical shock, DO NOT perform procedures involving cover or shield removal unless you are qualified to do so. DO NOT service or adjust alone. Do not attempt internal service or adjustment unless another person, capable of rendering first aid and resuscitation, is present. DO NOT substitute parts or modify equipment: Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized modification to the product. Return the product to a DEWETRON sales and service office for service and repair to ensure that safety features are maintained. Before opening the instrument (experts only) or exchanging the fuse in the power module disconnect power! Don’t touch internal wiring! Don’t use higher supply voltage than specified! Use only original plugs and cables for harnessing. The power-cable and -connector serve as Power-Breaker. For safety reasons max. 50 V may be applied to modules with BNC input-connectors! Refer to the regulation of maximum allowable touch potential. Safety of the operator and the unit depend on following these rules.

The time interval for recalibration depends on environmental conditions. Typically, the calibration should be checked once a year. Calibration certificates are available from DEWETRON as an option. DEWETRON offers two types: ISO traceable DEWETRON certificate Calibration certificate according to ÖKD (equivalent to DKD) This manual contains no calibration information. For self calibration, there is a separate Calibration Manual available.

Depending on the measurement mode (IEPE® sensors or voltage) the position of the switches at the input is changed. For all input channels the configuration can be changed individually except the level of the current source (4 mA or 8 mA). Changing the current range effects all eight sub channels. That means if the source level of channel 0 is set to 8 mA also channel 1 to channel 7 is switched to the same. But for channel 8 to channel 15 a different source level can be used. 24 MDAQ-SUB-ACC For constant current powered sensors (IEPE® mode) the current source is switched on and also the minus input of the BNC is connected to GND. The input coupling is switched to AC. In that mode also the TEDS interface circuit is allowed to read out the sensor information out of IEEE 1451.4 compliant sensors. In all voltage measurement modes the current source is disconnected from the input signal. The position of the GND switch defines if the amplifier is used for differential or singled ended input configuration. The allowed input voltage range (common mode voltage) is limited to ±13 V. NOTE: If floating input sources (like batteries) are connected to the MDAQ-SUB-ACC the amplifier has to be used in single ended configuration (GND-switch ON)! Otherwise the input may be out of the maximum input voltage range! In differential mode as well as in single ended mode AC or DC coupling is possible. The standard high pass filter frequency is 3 Hz in AC-mode. Please contact DEWETRON for other frequencies.

It provides Microdot input connectors and the possibility to switch the input channels to a free definable reference signal. Eight LEDs show the status of the IEPE® supply of every channel. The input multiplexer is realized with a mechanical relay to avoid signal distortions. The status of the mechanical relay is controlled via a reference voltage control. Low level on the reference voltage control is for measuring mode, high level on the reference voltage control switches the input channels to the reference signal. Changing the reference voltage control input affects all eight sub-channels. Every channel is equipped with a status-LED. It shows the status of the IEPE® excitation voltage and also the sensor supply. If the input channel is open - if there is no sensor connected to the input or the connection is defective (open circuit) - the IEPE® excitation voltage is near the upper limit. In this case the sensor check unit gives out no voltage and the LED is off. If the input channel is short-circuited the IEPE® excitation voltage is very low and the sensor check unit controls the LED to shine red. Is the IEPE® excitation voltage in the valid range a correct connected IEPE® sensor is assumed, the sensor check unit controls the LED to shine green. The sensor check unit isn’t able to check if the sensor measures correct values!

Frequently asked questions
The MDAQ-SUB-V-200-xx module offers programmable voltage ranges, both with and without a divider. Without the divider, the ranges are ±0.125 V, 0.25 V, 0.5 V, 1 V, 1.25 V, 2.5 V, 5 V, and 10 V. With the divider, the ranges are ±2.5 V, 5 V, 10 V, 20 V, 25 V, 50 V, 100 V, and 200 V.
The MDAQ-SUB-ACC-A module supports both IEPE® sensors and voltage-based sensors. It allows for both AC and DC coupled measurements with two selectable high pass filter options.
The DEWE-MDAQ series provides two output voltage options: ±5 V and ±10 V. The ±10 V option is available when using the MDAQ-BASE-10 module.
