Instruction Manual HYDACLab® 03.03.2008 1. Introduction If you have any questions regarding the technical data or suitability of the product for your applications, please contact our Technical Sales Dept. HYDACLab® sensors have been individually calibrated on computerized testing stations and subjected to final testing and operate perfectly when used according to the specifications (see Section 8. “Technical Data”). If any problems should nevertheless, arise, please contact HYDAC Service.
Instruction Manual HYDACLab® 03.03.2008 4. Functions HYDACLab® sensors are compact, multi-functional sensors for determining the condition of fluids online. Operators are kept informed of changes in fluid condition as they occur and can immediately change the operating conditions accordingly.
Instruction Manual HYDACLab® 03.03.2008 4.2 Analogue Output Analogue output signals representing measured values are output sequentially to Pin 4, when synchronization with the controller interfaced to the sensor is required. The sequencing of the signals involved is as shown in the diagram below: I Start 20mA Rel. visc. Rel. DC Start Rel. humidity Status Temp. 4mA 2s 2s 30s t All signals output to the analog output are 4 ..
Instruction Manual HYDACLab® 03.03.2008 5. Sensor Startup HYDACLab® sensors start storing data as soon as they have been connected to the supply voltage and fluid temperature has exceeded 25°C for the first time. The output signals for temperature and relative humidity are available immediately following sensor startup. The output signals for relative changes in viscosity and in dielectric constant are set to 12 mA during the referencing phase.
Instruction Manual HYDACLab® 03.03.2008 6.2 Reset via PLC control To connect the HYDACLab® to the PLC control a voltage divider must be provided on the PLC switch output as per the diagram below. PL C U PLC R1 H LB1 000 Pin 5 12 VDC ±0.5V R2 Over a period of 8s the HYDACLab® detects a cycle of high-low pulses and resets the sensor. In normal operating conditions, the level at PIN 5 must be 12 VDC ± 0.5 V.

Instruction Manual HYDACLab® 03.03.2008 12. Display Units 12.1 HDA 5500-0-2-zC-006 The HDA 5500, modification no. 006, is a display unit with 4 programmable switching outputs, which have been specially designed for use with HYDACLab® sensors. It is possible to display the actual measured values using the HDA 5500. Part no.
Instruction Manual HYDACLab® 03.03.2008 12.3 HMG 3000 Portable data recorder with a colour display with full graphics capability to display or record measured values from the HYDACLab®. The stored data of the HYDACLab® can be read out, displayed as a curve and archived. In addition, the HMG 3000 can be used to change the parameters and reset the HYDACLab. With the HMG 3000, the actual measured values and the stored measurement curves can be shown on the HMG 3000 display.
Instruction Manual HYDACLab® 03.03.2008 13. Functionality of the HYDACLab® HLB 1008-1C-001-F1 (programmable) additional to that of the standard model In addition to the standard functions it is possible to configure the HYDACLab®, modification no. 001 under menu point "Sensor dialogue" with the aid of the HMG 3000 and the PC software CMWIN.
Instruction Manual HYDACLab® 03.03.2008 13.1.1 Reset sensor (Reset function) In the sub-menu "Reset sensor", if you confirm with "OK", the sensor will be reset to its initial state (see Section 6 "Reset function"). Any stored data, including the referencing phase, will be completely deleted; the settings for the analogue or switching outputs are retained. An error message will appear which can be ignored. If you press "Cancel" you return to the main menu without resetting the sensor. 13.1.
Instruction Manual HYDACLab® 03.03.2008 13.1.3 Output 2 At this menu point, output 2 can be configured as a switching or analogue output. In addition it is possible to read out all measured variables sequentially using the analogue output. • Analogue output See description of the analogue output for output 1. • Switching output See description of the analogue output for output 1.
Instruction Manual HYDACLab® 03.03.2008 15. Important tips at a glance • For hydraulic applications, we recommend that the sensor is fitted in a vertical position with the electrical connector pointing downwards. • When installing the sensor, ensure that it is totally immersed in the fluid and that the fluid can circulate freely through the sensor. • Ensure there is constant flow and prevent the formation of air bubbles. With standing oil, variations in measurement may increase.
