Function
The evaluation system SB4 is an ESPE of type 4 (EN 61496-1 or IEC 61496-1) or category 4 (EN 954-1). This system is also designed and tested according to IEC 61508. It meets the requirements for the SIL3.
The operating instructions supplied with the device must be observed for planning, installation and operation.
A maximum of 4 safety light barriers can be connected to the evaluation device.
With the sensor card on position 2, it is possible to connect “3-wire” light barriers of the SLA family (for example SLA5) and light grids of the SLP type. But also p-switching safety devices with dedicated cross circuit monitoring can be connected, for example safety light curtains from the SLC family. In addition switch-off mats of the 4-wire principle or integrated safety sensors in the 1 or 2 channel version can be connected.
The cable or the manner it is laid to the light barriers and light grids must be chosen that no short circuit between the receiver and transmitter wires is possible.
Light curtains with semiconductor switch outputs and integrated safety sensors in 2 channel design are monitored for simultaneousness. The monitoring time is 2 s.
The connection is done on channels 3 and 4 and/or 1 and 2. Note that these sensors must feature a dedicated cross circuit monitoring, because the module does not carry out the cross circuit monitoring for these sensors. Integrated safety sensors, which are connected to the Safebox must work according to the normally closed principle.
An open contact means “safe status”. Switch-off mats of the 4-wire principle can be connected to channels 1 and 2 and/or 3 and 4.
Operating modes
By default, the restart interlock is activated.
Each assembly contains DIP switches for selecting the functions. For selecting
functions, 2 selector switches must always be actuated.
Switches on the first assembly:
| Switch | Position | Operating mode |
|---|---|---|
| 1 and 3 | OFF | Without restart interlock (restart, RI) |
| ON | With restart interlock (restart, RI) | |
| 2 and 4 | OFF | Without relay monitor (RM) |
| ON | With relay monitor (RM) |
Switches on the second assembly:
The assembly contains 6 DIP switches for selecting the sensor types and the position. Six possibilities are offered for combining sensors. The desired combination is to be set binary. Two switches must always be actuated in order to select a function, e.g.
DIP switches 1–3 have the same switch position as DIP switches 4–6.
| DIP switch | Operating mode |
|---|---|
| 3 and6 | 2 and5 |
| 0 | 0 |
| 0 | 0 |
| 0 | 1 |
| 0 | 1 |
| 1 | 0 |
| 1 | 0 |
Displays
The OSSD-R/supply module on position 1 has a red/green LED for indicating the OSSD on/off statuses, a yellow LED for the startready status and a 7 segment display for system diagnosis.
The 7 segment display indicates the status and the error codes of the system.
| Displ ay | 7 segment display |
|---|---|
| 1 | DIP switch positions differ |
| 2 | Incorrect configuration |
| 3 | Time-out at one or more muting sensors |
| 4 | Transmitter error |
| 6 | Muting lamp error |
| 7 | Simultaneousness monitoring error |
| 8 | Receiver error |
| 9 | Error at sensor channel |
| C | Error at sensor channel |
| E | System error |
| F | Relay monitor error |
| H | Selection chain error |
| L | Configuration error |
| U | Low voltage or voltage surge detected |
