HIMatrix Safety-Related Controller F31 02 Manual

HIMatrix Security Controller F31 02 Руководство

Product Description 

 The safety-related F31 02 controller is a compact system in a metal housing with 20 digital inputs and 8 digital outputs. The controller is available in various model variants for SILworX and ELOP II Factory, see Table 4. The device is suitable for mounting in Ex-zone 2, see Chapter 4.1.4. The device is TÜV-certified for safety-related applications up to SIL 3 (IEC 61508, IEC 61511 and IEC 62061), Cat. 4 and PL e (EN ISO 13849-1) and SIL 4 (EN 50126, EN 50128 and EN 50129). Further safety standards, application standards and test standards are specified in the certificates available on the HIMA website.

Safety Function 

 The controller is equipped with safety-related digital inputs and outputs.

Safety-Related Digital Inputs The controller is equipped with 20 digital inputs. The state (HIGH, LOW) of each input is signaled by an individual LED. Mechanical contacts without own power supply or signal power source can be connected to the inputs. Potential-free mechanical contacts without own power supply are fed via an internal short circuit-proof 24 V power source (LS+). Each of them supply a group of 4 mechanical 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.

Reaction in the Event of a Fault 

 If the device detects a fault on a digital input, the user program processes a low level in accordance with the de-energized to trip principle. The device activates the FAULT LED. In addition to the channel signal value, 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.

Line Control 

 Line control is used to detect short-circuits or open-circuits and can be configured for the F31 system, e.g., on EMERGENCY STOP inputs complying with Cat. 4 and PL e in accordance with EN ISO 13849-1. To this end, connect the digital outputs DO 1 through DO 8 of the system to the digital inputs DI of the same system as follows:

The controller pulses the digital outputs to detect the line short-circuits and open-circuits on the lines connected to the digital inputs. To do so, configure the Value [BOOL] -> system variable in SILworX or the DO[01].Value system signal in ELOP II Factory. The variables for the pulsed outputs must begin with channel 1 and reside in direct sequence, one after the other. If the following faults occur, the FAULT LED located on the front plate of the controller blinks, the inputs are set to low level and an (evaluable) error code is created: 

  Cross-circuit between two parallel wires. 

  Invalid connections of two lines (e.g., DO 2 to DI 3), 

  Earth fault on one wire (with earthed ground only). 

  Open-circuit or open contacts, i.e., including when one of the two EMERGENCY STOP switches mentioned above has been engaged, the FAULT LED blinks and the error code is created.

Safety-Related Digital Outputs The controller is equipped with 8 digital outputs. The state (HIGH, LOW) of each output is signaled by an individual LED (HIGH, LOW). At the maximum ambient temperature, the outputs 1...3 and 5...7 can be loaded with 0.5  A each; and outputs 4 and 8 can be loaded with 1 A or with 2 A at an ambient temperature of up to 50 °C. If an overload occurs, one or all digital outputs are switched off. If the overload is removed, the outputs are switched on again automatically, see Table 17. The external wire of an output is not monitored, however, a detected short-circuit is signaled.
