HIMatrix Safety-Related Controller F31 02 Manual

1. Cross-circuit between two parallel wires.

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

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

4. 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.

3.5 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.

3.6 Reaction in the Event of a Fault

If the device detects a faulty signal on a digital output, the affected module output is set to the safe (de-energized) state using the safety switches.If a device fault occurs, all digital outputs are switched off.In both cases, the devices activates the FAULT LED.The error code allows the user to configure additional fault reactions in the user program.

3.7 Structure

This chapter describes the layout and function of the controller, and its connection for communication.

LED Indicators

The light-emitting diodes (LEDs) indicate the operating state of the controller. The LEDs are classified as follows:

1. Operating voltage LED

2. System LEDs

3. Communication LEDs

4. I/O LEDs

Function and meaning of the system LEDs and communication LEDs depend on the CPU operating system (and thus on the COM operating system).When the supply voltage is switched on, a LED test is performed and all LEDs are briefly lit.Definition of Blinking Frequencies The following table defines the blinking frequencies of the LEDs:The key can be accessed through a small round hole located approximately 5 cm from the upper left-hand side of the housing. The key is engaged using a suitable pin made of insulating material to avoid short-circuits within the controller.The reset is only effective if the controller is rebooted (switched off and on) while the key is simultaneously engaged for at least 20 s. Engaging the key during operation has no effect.

Properties and behavior of the controller after a reboot with engaged reset key:

1. Connection parameters (IP address and system ID) are set to the default values.

2. All accounts are deactivated except for the administrator default account with empty password.

3. With COM operating system version 10.42 and higher, loading a user program or operating

system with default connection parameters is inhibited!

The loading procedure is only allowed after the connection parameters and the account have been configured on the controller and the controller has been rebooted.After a new reboot without the reset key engaged, the connection parameters (IP address and system ID) and accounts become effective.

1. Those configured by the user.

2. Those valid prior to rebooting with the reset key engaged, if no changes were performed.
