Frequently Asked Questions - ER5018 OMRON

How to install the ER5018 switch?

Installation must be carried out by qualified personnel. Secure the device with M5 screws (tightening torque 4 Nm). Tension the rope to the middle position indicated by the red arrows in the viewing window. Use rope supports every 2.5 to 3 m.

What is the function of the blue reset button?

The blue reset button allows the switch to be returned to the run position after a trip. It must be manually pressed to allow the machine to restart.

How to test the proper operation of the system?

Actuate the rope at different points in the protected area. Check that the switch opens and the machine stops. Press the blue button to reset. Repeat the test to ensure reliable operation.

What is the maximum rope reach?

The maximum rope reach is 40 meters. For longer distances, install a second switch at the end.

What are the normal operating conditions?

Pulling force less than 75 N and rope deflection less than 150 mm between eye supports. Tension must be adjusted to maintain these values.

Is the switch resistant to water washdown?

Yes, the IP67 (NEMA 6) rating allows cleaning with water jets. Ensure that the cable glands are properly tightened (torque 1.5 Nm) to maintain the seal.

What safety contacts are available?

The safety contacts are normally closed (NC) with the rope properly tensioned. Two possible configurations: 2 NC + 1 NO or 3 NC.

Can an additional emergency stop button be added?

Yes, the switch can be equipped with a red emergency button (optional) mountable in two positions. It is also available as an accessory (SM06-ES60).

What accessories are available for the ER5018?

Rope kits (RK5, RK10, RK20, RK50), rope only, pulley, tensioner, spring, thimble, etc. Refer to the accessory table in the manual.

How to maintain the switch?

Check operation and rope tension weekly. Every 6 months, cut power, remove the cover, check the tightness of terminals and absence of moisture. Never attempt to repair the device.

• IP67 (NEMA 6) enclosure enables the ER5018 switch to withstand water washdown cleaning
• Heavy-duty housing—the die-cast housing and stainless steel eye nut makes the ER5018 suitable for demanding industrial applications
• Integral E-Stop—the optional E-stop provides emergency stopping at the extreme end of the installation
• Reset button—the blue reset button must be pushed in order to return to "machine run" condition following switch actuation by a pulled or slacked rope
• Long life—the ER5018 switch is designed for a minimum of one million actuations
• Vibration tolerant—the snap-acting switch contacts protect against nuisance tripping due to vibration

Operating instructions

Installation must be in accordance with the following steps and stated specifications and should be carried out by suitably competent personnel. Adherence to the recommended maintenance instructions forms part of the warranty.

WARNING

Do not defeat, tamper, remove or bypass this unit. Severe injury to personnel could result.

Optional 24 VDC Indicator Beacon

When +24VDC is applied to the red wire, the beacon will illuminate red and flash.

When +24 VDC is applied to the green wire, the beacon will illuminate green.

Optional 120 VAC Indicator Beacon

When +120VAC is applied to the red wire, the beacon will illuminate red and flash.

When +120 VAC is applied to the green wire, the beacon will illuminate green.

Tension Indicator

Indicator shown with steel rope properly adjusted.

WARNING

1. Installation of all Safety Rope Switch systems must be in accordance with a risk assessment for the individual application. Installation must only be carried out by competent personnel and in accordance with these instructions.
2. Rope support eyebolts must be fitted at 2.5m min. to 3m max. intervals along all rope lengths between switches. The rope must be supported no more than 500mm from the switch eyebolt or Safety Spring (if used). It is important that this first 500mm is not used as part of the active protection coverage.
3. M5 mounting bolts must be used to fix the switches. Tightening torque for mounting bolts to ensure reliable fixing is 4Nm . Tightening torque for the lid screws, conduit entry plugs and cable glands must be 1.5Nm to ensure IP seal. Only use correct sizing glands for conduit entry and cable outside diameter.
4. Tensioning of rope is achieved by use of tensioner / gripper assemblies. Upon installation, tension to mid-position as indicated by the red arrows in the viewing window of each switch. Check operation for all switches and the control circuits by pulsing the rope at various locations along the active protection area and resetting each switch by depressing the Blue Reset button. Ensure each time that the switches latch off and require manual resetting by depressing the Blue Reset button. Increase the system tension further, if required, depending upon the checks along the active length of coverage. If fitted with a Mushroom type E-Stop button (Red) then test and reset each switch to ensure function of control circuits. Typical operational conditions for successful operation of system is less than 75 N. pulling force and less than 150mm deflection of rope between eyebolt supports. If the optional LED is fitted but is not used, ensure that the conductors remain coiled and tied to the tie hole in the LED flange.
5. Every week: Check correct operation of system at locations along all coverage length. Check for nominal tension setting, re-tension rope if necessary. Every 6 months: Isolate power and remove cover. Check screw terminal tightness and check for signs of moisture ingress. Never attempt to repair any switch.
