operating instructions signo 727 SSI Position-Indicator with/without limit values and SSI input from absolute encoder 1. 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 SELF SOURCE (12-24VDC versions) according to EN 60 950, 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! Contents 1. Safety instructions 1 2.

Technical data 6 7.1 Ordering information 7 7.2 Accessories 7 7.3 Explanation of technical terms 7 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. MEYLE 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. Seite1/7
2. Mounting of the position indicator Mounting and dimensional drawing (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 Terminal connections Attention: Take care that all parts of system are deenergized 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 100...240 VAC! To maintain interference grade 3, all count and control lines shall be shielded. The supply lines should be routed in separate channels. 2.2.1 Connection AC-Version: here with limit values DC-Version: here without limit values Seite2/7

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. Example 1: (set value = 0) count impulses Example 2: (set value between limit value 1 and limit value 2) count impulses limit value 2 limit value 2 limit value 1 t set value limit value 1 t Out1 Out1 Out2 Out2 3.
