HIMatrix F35 Safety-Related Controller

HIMatrix  F35 Safety-Related Controller

Product Description 

The safety-related F35 controller is a compact system located in a metal enclosure with 24 digital inputs, 8 digital outputs, 2 counters and 8 analog inputs. The controller is available in 3 model variants for SILworX and 3 model variants for ELOP II Factory, see Chapter 3.2. All variants are described in this manual. The device is suitable for mounting in Ex-zone 2, see Chapter 4.1.5. The device has been certified by the TÜV for safety-related applications up to SIL 3 (IEC 61508, IEC 61511 and IEC 62061), Cat. 4 (EN 954-1) and PL e (EN ISO 13849-1). Further safety standards, application standards and test standards are specified in the certificate available on the HIMA website.

Safety Function The controller is equipped with safety-related digital inputs and outputs, safety-related counters and safety-related analog inputs.

Safety-Related Digital Inputs The controller is equipped with 24 digital inputs. The state (HIGH, LOW) of each input is signaled by an individual LED. The input signals are captured as analog measurements and provided to the program as a range of INT values from 0...3000 (0...30 V). Configurable thresholds are used to generate BOOL values, see Table 26 The default setting is: Low level: < 7 V High level: > 13 V The thresholds are set using system parameters taking the safety-related accuracy into account, see Table 43 and Table 44.

The LEDs for the digital inputs are activated by the program if the F35 is in RUN.

Mechanical contacts without own power supply or signal power source can be connected tothe inputs. Potential-free mechanical contacts without own power supply are fed via ainternal short-circuit-proof 24 V power source (LS+). Each of them supply a group of 8mechanical contacts. Figure 1 shows how the connection is performed.With signal voltage sources, the corresponding ground must be connected to the input (L-),

see Figure 1. 

Safety-Related Counter The controller is equipped with 2 independent counters with inputs that can be configured for 5 V or 24 V voltage level. The required voltage level is determined by the user program with the Counter[0x].5/24V Mode system parameter. Input A is the counter input, B is the count direction input and input Z (zero track) is used to reset. Alternatively, all inputs are 3-bit Gray code inputs (in decoder operation) The following modes of operation can be implemented: ƒ Counter function 1 (depending on the count direction input signal) ƒ Counter function 2 (not depending on the count direction input signal) ƒ Decoder operation with attached absolute rotary transducer Refer to Chapter 3.4.4 for the description of the counters configuration. The safety-related counter has a 24-bit resolution, the maximum counter reading is 224 - 1 (= 16 777 215).

Reaction in the Event of a Fault If the device detects a fault in the counter section, a status bit is set for evaluation in the user program. The device activates the FAULT LED. In addition to the status bit, the user program must also consider the corresponding error code. The error code allows the user to configure additional fault reactions in the user program.

During two-pole-pole operation, a line diagnosis is performed to detect potential external short-circuits to L+ and L-. Time on delay is required to detect external short-circuits with an inductive or capacitive load or a lamp load. This delay can be configured using the Time on delay system parameter. In the range of 0...30 ms, the value can be set in steps of 1 ms.
