Safety Relay Modules HR6S 

## Safety Relay Modules 

Improve productivity with predictive maintenance of safety systems 

## Safet Rela Modules for IoT y y 

The basis of a functional safety system is to use diagnosis to detect failures. 

Redundant control systems, for example, maintain safety by detecting the occurrence of a single failure, and at the same time give user the opportunity to replace parts. This concept, which was introduced through international standards in 1999, has adopted throughout the world the idea of safety by control based on safety relay modules. * S 

With the recent progress of IT technology, IoT is being promoted at factories around the world for the purpose of optimizing productivity. The optimal allocation of resources and predictive maintenance are important in such factories. However, predictive maintenance for safety systems that directly influence machine operation is especially important, and is indispensable for achieving both productivity and safety. 

The HR6S safety relay module has advanced diagnostic functions, and can output the results. The diagnostic function, which is backed by international standards, monitors the safety relay module and the devices that are connected to it, and contributes to predictive maintenance for the safety system.

HR6S SAFETY RELAY MODULE 

## Connect to Various Input Devices 

Dials are used to select input devices and start functions to enable safety measures for a wide variety of machines and allows standardization of the relay module. 

## Setting a start function 

Select from 8 types of start functions without changing the wiring. Automatic and manual operation can be selected as well as "startup test", which requires monitoring, cross-circuit detection, and pre-start inspection. 

(For details, see page 28.) 

## S ~~e~~ tting a ~~n a~~ pplicatio ~~n fun~~ ction 

Set up to 7 types of input devices, such as emergency stop switches, interlock switches, light curtains, RFID devices, magnet switches, proximity switches, two-hand control switches, and pressure-sensitive switches.

## Protection 

A sealing strip to secure the protective cover is included, preventing the dials from inadvertent adjustment or settings from being changed. 

P R O T E C T I V E C O V E R 

## Output Expansion 

Outputs can be expanded (excluding HR6S-AB). No wiring is required, because expansions are connected via the connector on the side of the unit.

- First, determine the PLr and category of the safety system. 

- *1: NC contacts are compatible with category 1 and PLc. 

- *2:  Although both "√" and "√√" can be connected, models indicated with "√√" is recommended for use. When inputting multiple input devices in parallel, select either HR6S-S or HR6S-DN. 

- *3: When connecting toHR6S-AT, use the selector to select instantaneous or delay. 

- *4: Non-safety-related instantaneous output available. 

- *5: 5 types - 0.25 s, 0.5 s, 1 s, 2 s, and 4 s. 

## Performance level of facilities and applicable models 

- When defining the performance level of machines, a risk assessment must be performed for each machine.

## HR6S-AT Safety Relay Module 

## Equipped with time delay output for Stop Category 0 and Stop Category 1 

- Protects both the operator and the machine by immediately stopping dangerous movements (stop category 0) when instructed to stop by the operator or or when a failure in the safety circuit is detected. Also, the safety module is equipped with a stop category 1 delay output, which allows the motor to stop after deceleration.

- The selector on the front can be used to set the delay time to a value from 0.1 seconds to 15 minutes. (Can also be set to 0 seconds.) 

- The delay output can be canceled by the S21-S22 or S31-S32 terminal (vacant terminal), and the delay output is immediately cut off when canceled.

- *8)  HR6S checks the pulse of Y1 to detect short-circuit between other input wires and power supply wires, so when 24V signals are input to Y2 from PLCs, select start mode when dynamization is "No". 

## Status Monitor by Diagnosis (Example for HR6S-AT) 

## Explanation of Status Output 

The HR6S diagnoses and monitors connected devices, and can output the results to the Tr output (not safety-related). The status monitor outputs a pulse signal instead of I/O. 

The length of the diagnostic bit sequence output from status output Z1 is 2 s. The configuration is a 10-bit signal where each bit is 200 ms. The first 4 bits (0010) are the start codes that represent the start of the bit sequence. The next 6 bits are a diagnostics code that indicates the status of the HR6S. 

The cycle time (scan time) of the task that executes the program must be 50 ms or less for the bit sequence to be detected correctly. A ladder program for decoding by PLC is provided. (For IDEC FC6A PLC)

Note 1:  If the status of the HR6S changes during the output of the bit sequence, it will be sent in the next sequence. Therefore, the maximum delay in status output for a change of status is 4 s. 

However, if the running bit sequence does not last until the next sequence starts (if status changes occur within 2 s), it will not be sent in the next sequence. 

Note 2:  Turning off the power connected to the HR6S safety module can cause the ladder program to detect incorrect status information.

## Safety measures for low risk machines Category 2 Safety Relay Module 

## Introducing a safety system for low risk machines 

Designing a category 2 system has been difficult and only a redundant system (category 3) could be used to protect machines against relatively minor hazards. 

However, with the HR5S safety relay module, designing a category 2 system is easy and enables cost reduction and saves maintenance time. 

See IDEC website for more details.
