EVALUATION UNIT G1506S

PAGE 13 ENGLISH2. Function and features The evaluation unit is a redundant diverse system to process a chain of sensors with up to 8 fail-safe switches. The evaluation unit supplies/monitors the connected fail-safe switches and evaluates their switching status. If all fail-safe switches are fully operational and correctly damped, the evaluation unit transmits the safety code table to the AS- interface (8x4 bit data sequence). The safety-related evaluation of the code table must be effected by a suitable safety monitor (e.g. AC001S, AC002S, AC003S, AC004S). The safe state is when no code is transmitted (static 0). The evaluation unit complies with the category 4 according to EN 954-1 or the re- quirement class 5 according to DIN V 19250/DIN V 19251 and DIN V VDE 0801. Depending on the safety components used the complete safety system can also be classified in a lower safety category! Notes on functions and features

• AS-i chip according to the AS-interface version 2.1

3. Configuration requirements

The following requirements must be complied with when using the evaluation unit G1506S. Hardware-dependent requirements The safety requirements of the respective application must correspond to the re- quirements stated in these instructions. The specified technical data must be complied with. By taking administrative measures in the application it must be ensured that a function check is carried out at least once a year. A function check is carried out by switching the AS-i supply voltage or the evaluation (data bit DO0, 0 = evalua- tion ON) briefly off. In case of faults within the evaluation unit which result in the defined safe state, the evaluation unit must be replaced. Software-dependent requirements The complete description of the configuration of the AS-i safety monitor has to be taken into account!

Setup Installation Mount the evaluation unit onto a wired AS-i FC or FC-E coupling module and then onto a 35 mm rail or fasten it onto a mounting device. Electrical connection The supply of the fail-safe switches comes from the AS-i system. Do not connect the inputs with an external potential. Connect the M12 socket I-1 of the evaluation unit to the corresponding connec- tions of the fail-safe switch or the chain of fail-safe switches (L+, TE, L- and OUT). When the switching output O-3 is used, an FC-E coupling module must be used! Cover the possibly unused socket O-3 with the enclosed protective cap to main- tain the specified protection rating. Parameter setting Depending on the number of connected fail-safe switch versions the parameters must be set.

Fail-safe switch Even number Odd number GI5002 D01=1 D01=0 GM503S D01=1 D01=0 GM504S D01=1 D01=1 GM505S D01=1 D01=1 GI505S D01=1 D01=1 GG505S D01=1 D01=1Addressing The address has been set to 0 at the factory. Assign a free address between 1 and 31. Addressing with the addressing unit AC1144 If the mounted and wired module is used with the FC coupling module AC5010 (with addressing socket), it can be addressed via the addressing cable (E70213). Addressing via the addressing socket is only allowed when the evaluation unit is disconnected. If it is used with the FC coupling module AC5000 (without addressing socket) the evaluation unit must first be addressed via the addressing unit AC1144 and then mounted onto the lower part. Infrared addressing The evaluation unit also offers the option of infrared addressing with the address- ing unit AC1144. The AS-i communication (yellow cable) must be switched off during the infrared addressing. To do so, disconnect the master. When the ifm AS-i power supplies type SL are used, the communication can be deactivated via a plug on the power supply. Supply the slaves with voltage via the AS-i power supply. Infrared addressing is carried out via the IR addressing cable E70211.

The response time of the evaluation unit to a safety request is max. 220 ms. Within this period the safety code 0000b (=safe state) is statically transferred. Calculation of the total response time For the calculation of the response time of the total system the response times of the other components also have to be added (fail-safe switch, evaluation unit, safety monitor and possibly external relays). Example: For the fail-safe switch GM503S the response time to a safety request is < 20 ms and for the safety monitor AC001S < 40 ms. The sum of the individual response times results in the total response time to a safety request of < 280 ms. The switching times of external relays also have to be added.

PAGE 189. Fault diagnosis If after power on the evaluation unit is not enabled, a system fault is assumed. In the easiest case a connected fail-safe switch is not in the operating range. Location by means of the indicators Wiring and sensor faults One way to locate wiring or sensor faults is the indication of the enable signal of the connected inductive fail-safe switches (LED 1, see the figure on page 16). The connected fail-safe switches can be wired pseudo-serially, i.e. the clock or the enable signal is passed through from the first to the last connected fail-safe switch. If somewhere in this chain one or several faults occur, the enable signal is interrupted starting from the first detected fault source. The LED 1 yellow provides the information whether all connected fail-safe switches have given the enable signal. Internal faults If the evaluation unit detects a fault, the unit changes to the safe state (LED 4 red, see figure on page 16). A function test of the evaluation unit allows to check whether a hardware error is present or whether the change to the safe state has been caused by external faults. To do so the evaluation has to be switched off briefly for min. 50 ms (data bit DO0, 1= evaluation OFF, also see page 21). Voltage supply If after power on the LED green PWR is not lit, the supply voltage must be checked. Overload and short circuit of the input supply are signalled to the AS-i master (version 2.1) via the "periphery fault" flag in the status register.

10. Maintenance/duration of use

The evaluation unit is maintenance-free. The maximum duration of use is 10 years.
