COMPACT AND STANDARDS-COMPLIANT SAFETY DEVICES

Emergency stop (E-stop) switches are a fundamental safety element for all types of automation, but compact equipment sizes and increasing regulatory requirements are challenging designers to find better ways of incorporating E-stops. The IDEC XA/XW short-body E-stops address this, featuring a minimal installation footprint and meeting the requirements of ISO13850:2015 by illuminating the cap in red when the E-stop is functional (Active) to be used in an emergency, and turning white when the E-stop is not-functional (Inactive). With additional safety and durability features, designers now have more choices to ensure standards-compliant safety in industrial applications.

Emergency stop function on portable operator control stations

With the growing advancements in technology, users have been demanding more convenient and efficient options such as using detachable cables that allow a single teaching pendant to be used with multiple robots or eliminating the need for wiring. However, safety remains a crucial aspect that must be considered with utmost care. Therefore, the requirements for detachable and wireless operator control stations have been updated in this revision to ensure maximum safety and reliability.

ISO13850: 2015
4.3.8.——————————————————————————————————————————————————————————————————————————————————————————————————————–
When emergency stop devices are installed on detachable or cableless operator control stations (e.g. pluggable portable teaching pendants), at least one emergency stop device shall be permanently available (e.g. in a fixed position) on the machine.

In addition, at least one of the following measures shall be applied to avoid confusion between active and inactive emergency stop devices:

• device colour changing through the illumination of the active emergency stop device;
• automatic (self-actuating) covering of inactive emergency stop devices; where this is not practicable, manually-applied covering may be used, provided that the cover remains attached to the operator control stations;
• provision of proper storage for detached or cableless operator control stations.

The instructions for use of the machine shall state, which measure has been applied to avoid confusion between active or inactive emergency stop device(s). The correct operation of this measure shall be explained.

Intended actuation

Recommended actuators and nameplates

• To ensure a quick and effective response in case of an emergency, it is crucial to optimize the operability and visibility of the emergency stop switch.
• The switch should be easily accessible and actuated with intent and without any hesitation.
• Therefore, the following safety requirements are included.

ISO13850:2015

• 4.1.1.2————————————————————————————————————————————————————————————————————————————————————————————————————————-
• The emergency stop function must be available and operable at all times.
• 4.3.6—————————————————————————————————————————————————————————————————————————————————————————————————————————-
• The actuator of the emergency stop device shall be coloured RED. As far as a background exists behind the actuator and as far as it is practicable,
• the background shall be coloured YELLOW.
• 4.3.7——————————————————————————————————————————————————————————————————————————————————————————————————————————
• Neither the actuator nor the background should be labelled with text or symbols.
• When it is necessary to identify the direction of unlatching of the actuator (button) then this identification shall have the same or nearly the same colour as the actuator.

Intended resetting

Importance of human intention in resetting

• In emergencies, an emergency stop switch requires an intentional action to be triggered. As such, it is also essential to consider the intended action required to reset the emergency stop switch as part of the safety requirements.

ISO13850:2015

• 4.1.1.2——————————————————————————————————————————————————————————————————————————————————————————————————————————
• The emergency stop function shall be reset by intentional human action. Resetting of the emergency stop function shall be operated by disengagement of an emergency stop device.

Example (IDEC XA series)

• The NC contact does not move until the emergency stop switch latches (locks), allowing OFF operation and resetting only by the intended operation.
• The safety lock feature allows only the intended reset to operate.

Applications

• Emergency stop switches are vital safety components used across various industries to prevent accidents and ensure worker safety.
• The new compact and short-body design XA/XW series offers a wider range of applications, making it a versatile and reliable solution for emergency stop needs.

• Turn off the power to the product before starting installation, removal, wiring, maintenance, and inspection of the products. Failure to turn the power off may cause electrical shock or fire.
• Use wires of the proper size to meet the voltage and current requirements. Incorrect wiring causes overheating, resulting in a possible fire hazard. Provide appropriate protection against electric shock. Failure to turn the power off may cause electrical shock or fire.

Instructions

Panel mounting
Notes for panel mounting Do not tighten with excessive force using tools such as pliers. Otherwise, the locking ring may be damaged.

XA series
Remove the locking ring from the operator and check that the rubber gasket is in place. Insert the operator from the panel front into the panel hole. Install the locking ring with the recommended tightening torque by aligning the protrusion A of the operator with the panel hole groove. Using the locking ring wrench MT-001, tighten the locking ring to a torque of 0.8 to 0.9N·m.

X Series
Remove the locking ring from the operator and insert the operator from the panel front into the panel hole. Install the locking ring with the recommended tightening torque by aligning the protrusion B of the operator with the panel hole groove. Using the locking ring wrench MW9Z-T1, tighten the locking ring to a torque of 1.8 to 2.0N·m.

Wiring (Notes for solder terminal)

1. The applicable wire size is 1.25mm2 maximum. The wires should be soldered through the holes in the terminals.
2. Solder the terminals using a soldering iron at 310 to 350°C for within 3 seconds. Do not use flow or dip soldering. (Sn-Ag-Cu type leadfree solder is recommended.) When soldering, make sure to solder as far away as possible from the plastic part of the switch body. Do not apply external force such as bending the terminals or pulling the wires. Check the operation using the actual load.
3. Use a non-corrosive rosin-based flux. To prevent the flux from entering the switch while soldering, face the terminals downward.
4. Because the terminal spacing is narrow, use protective tubes or heat-shrinkable tubes to avoid burning the wire sheath or short circuit.
5. Apply force on the terminals in the vertical direction to the panel only, otherwise the terminals will be damaged.

Wiring (solder/tab #110 terminal)

1. Use quick connect #110 and 0.5mm tab thickness.
2. To prevent short circuits between different poles, use protective tubes or heat shrink tubes.
3. Apply force on the terminals in the vertical direction to the panel only, otherwise the terminals will be damaged.

Contact chatter/bounce

• Contact chatter/bounce may occur when the main contact (NC contact)
  • is reset by pulling or turning or when the monitor contact (NO contact)
  • is pressed. Take countermeasures to prevent chatter/bounce.
  • (Reference value: 20ms)
• Also, do not apply external shock to the switch as chatter may occur.

LED Illuminated Switches

• Illumination colors and illuminance may vary depending on the LED element and each product.
• An LED lamp is built into the contact block and cannot be replaced.

Notes

• Do not expose the switch to excessive shock and vibration, otherwise, the switch may be deformed or damaged, causing malfunction or operation failure.
