Safety instructions This instrument has been built and tested in accordance with EN 61010, part1 - Protection Measures for Electronic Measuring Instruments - and have left our works in safe and proper condition. In order to maintain these conditions and to ensure safe operation, the user must observe the instructions and warnings provided in these operating instructions. This units must only be operated if correctly installed! The supply voltage must be derived from a SELV SOURCE (12-24VDC versions) according to EN , since no galvanic separation is provided between power-supply and electronic in-/outputs! When mounting and installing the units, the instructions of the local suppliers of energy are to be considered. The unit must only be opened for setting by trained personnel. The plug-in terminals, at rear of the unit, must not be accessed before first isolating the supply. The identification numbers of the plug-in terminals and of the corresponding socket strip must be observed. Unassigned terminals (NC) may not be connected! Connection terminals are to be protected by installation! In order to ensure hand contact safety at the connection terminals, live wires must be connected properly to the connection terminals. If safe operation can no longer be ensured, the position indicator must be disabled and secured against accidential operation. Installation of electrical devices should only be carried out by a qualified electrican. Panel mounting devices should only be operated when proberly mounted in the panel. Before switching on, make sure that the power and control voltages do not exceed the values specified in the technical data. In a situation where failure of the device could cause harm to people, animals or property, additional safety measures must be employed, e.g. stop switches, protection devices etc. Hengstler counters are intended for industrial applications. The mounting and environment and nearby cabling have an important influence on the EMC (noise radiation and noise immunity) of the counter. When putting into operation, the EMC of the whole installation (unit) has to been secured. In particular, the relay outputs are to be protected from high noise radiation by suitable wiring. The range of applications for those products are industrial processes and controls, where the overvoltages applied to the product at the connection terminals are limited to values of the overvoltage category II.

2 2. Mounting of the position indicator Dimensions in mm 2.1 Mounting the position indicator into the panel. 1. Slide installation frame towards the rear and off the position indicator, lift the two self locking catch springs. 2. Turn back the screws of the installation frame by approx. 5 mm. 3. Insert position indicator into the cut-out of panel and snap installation frame into place 4. Fix the position indicator with the screws against the panel. 2.2 Connection Attention: Take care that all parts of system are de-energized during the installation of position indicator and that current is not switched on during assembly! Safety conditions are to be observed during installation, which shall be effected by trained personnel only. Caution: The operation and/or switched voltages can reach VAC! To maintain interference grade 3, all count and control lines shall be shielded. The supply lines should be routed in separate channels Terminal connections AC-Version: here without limit values DC-Version: here with limit values Sach-Nr Version 9/98 2/8

The bistable signal is active until the count value falls below the limit value or the counter is reset to zero. Reset to zero or to the set value is done manually from the keyboard or electrically from the reset input. Attention: Per default, the display range of the indicator is centered, i.e. in conjunction with a 4096 ppr encoder the display reaches from to By means of the reference value, however, the display can be adjusted to show 0 to Program a reference value of 2048, forward the workpiece to the middle position and reset the indicator. count impulses count impulses limit value 2 limit value 2 limit value 1 t set value limit value 1 t Out1 Out1 Out2 Out2 Example 1: (set value = 0) Example 2: (set value between limit value 1 and limit value 2) 3. Operation of the position indicator 3.1 Display and keyboard P1 P2 SET DATA CHAIN Area A: Display, in counting mode showing the actual or absolute position (chain value or absolute value), and in programming mode the changeable parameters. SSI Area B: LED indicators show in counting mode the chain value (chain) or the active output signal (limit value 1 = P1, limit value 2 = P2) 1 or to switch over to the absolute value (DATA). In programming mode the LED's are flashing, so pointing to the changeable parameter (set value = set). Area C: Keyboard: The use of the different keys is explained in chapter only for position indicators with limit values Sach-Nr Version 9/98 3/8

4 3. 2. Setting the reference value or reset of the chain value Explanation to chain value: The chain value (CHAIN) is a second display independent of the main counter. It does not influence the limit values and can be reset to 0 at any point. For example, as a display help when processing chain measured parts. Function Procedure Setting the absolute value to a When absolute value is displayed: Press simultaneously the buttons R and reference value Zerosetting of the chain value When chain value is dis-played (LED CHAIN illuminated): Press R-button. Cancelling reference value Press simultaneously the buttons R and 3.3 Changing of limitation value 1, limitation value 2 and set value Function Procedure Selection of limitation value 1 Press key F1 (LED P1 is flashing) Selection of limitation value 2 Press key F2 (LED P2 is flashing) Selection of set value Press key E and F1 simultaneously (LED SET is flashing) Changing parameters Press -key (arrow up) to change the value of the blinking digit. Press -Key (arrow left) to switch to the next digit. Change sign with the +/- key. Press R-key to reset the value to zero Storage of parameters Press E key shortly to exit and return to display mode Exit without storage by time criterion: the return to the display mode is automatically done 15 sec after the last pressing of a key, without storing the changed parameter 4.
