USER MANUAL ER5018 OMRON

Compact Rope Pull Emergency Stop Switch

ER5018

• Compact size allows this switch to be used on smaller machines with a mounting width of 40mm and covering rope spans up to 40m
• Tension indicator—the tension indicator makes the system easy to set up and to maintain the proper rope tension
• Contact arrangements of 2 ~N / C + 1 ~N / O or 3 ~N / C
• 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.
