Operating Instructions Transponder-Coded Safety Switch CTP-AR 1. About this document 1.1. Scope These operating instructions are valid for all CTP‑L.‑AR… from version V1.0.0. These operating instructions, the document “Safety information and maintenance” and any enclosed data sheet form the complete user information for your device. 1.2.
Operating Instructions Transponder-Coded Safety Switch CTP-AR 2. Correct use Safety switches series CTP‑L.-… are interlocking devices with guard locking (type 4). Devices with unicode evaluation possess a high coding level, devices with multicode evaluation possess a low coding level. In combination with a movable guard and the machine control, this safety component prevents the guard from being opened while a dangerous machine function is being performed.
Operating Instructions Transponder-Coded Safety Switch CTP-AR NOTICE For information about combination with an AR evaluation unit, please refer to chapter 10.10. Connection of several CTP‑AR in a switch chain on page 24. 3. Description of the safety function Devices from this series feature the following safety functions: Monitoring of guard locking and the position of the guard (interlocking device with guard locking according to EN ISO 14119) ÌÌSafety function (see chapter 6.8.
Operating Instructions Transponder-Coded Safety Switch CTP-AR Activation of guard locking If the device is used as guard locking for personnel protection, the control of the guard locking must be regarded as a safety function. The device does not feature a safety characteristic for the control of the guard locking, because the guard locking solenoid is completely disconnected from outside the device (no control function within the device). It therefore does not contribute to the failure probability.
Operating Instructions Transponder-Coded Safety Switch CTP-AR 4. Exclusion of liability and warranty In case of failure to comply with the conditions for correct use stated above, or if the safety instructions are not followed, or if any servicing is not performed as required, liability will be excluded and the warranty void. 5. General safety precautions Safety switches fulfill personnel protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Operating Instructions Transponder-Coded Safety Switch CTP-AR 6. Function The device permits the locking of movable guards. The system consists of the following components: coded actuator (transponder) and switch. Transponder-coded actuator Whether the device learns the complete actuator code (unicode) or not (multicode) depends on the respective version.
Operating Instructions Transponder-Coded Safety Switch CTP-AR The actuator cannot be pulled out of the switch and the guard is locked as long as the guard locking pin is extended. If a voltage is applied to the guard locking solenoid, the guard locking pin is retracted and the actuator is released. The guard can be opened. 6.7.
Operating Instructions Transponder-Coded Safety Switch CTP-AR 7. Manual release Important! No further release functions can be retrofitted on Extended variants with controls in position 1 (S1) and position 2 (S2). S1 S2 S3 Some situations require the guard locking to be released manually (e.g. malfunctions or an emergency). A function test should be performed after release. More information on this topic can be found in the standard EN ISO 14119:2013, section 5.7.5.1.
Operating Instructions Transponder-Coded Safety Switch CTP-AR 7.2. Emergency unlocking Permits opening of a locked guard from outside the danger zone without tools. For mounting, see the mounting supplement. Important! ÌÌIt must be possible to operate the emergency unlocking manually from outside the protected area without tools. ÌÌThe emergency unlocking must possess a marking indicating that it may be used only in an emer- gency. ÌÌThe actuator must not be under tensile stress during manual release.
Operating Instructions Transponder-Coded Safety Switch CTP-AR 7.4. Wire front release Release via a pull wire. Depending on the type of attachment, the wire front release can be used as emergency unlocking or escape release. The following applies to non-latching wire front releases. If the release is to be used as emergency unlocking, one of the following measures must be taken (see EN ISO 14119:2013, section 5.7.5.3): ÌÌInstall the release so that it can be reset only with the aid of a tool.
Operating Instructions Transponder-Coded Safety Switch CTP-AR 8. Changing the approach direction The approach direction needs to be changed only if the switch is to be approached from the rear. Proceed as follows: 1. Remove the screws from the safety switch 2. Set the required direction 3. Tighten the screws with a torque of 1.
Operating Instructions Transponder-Coded Safety Switch CTP-AR 9. Installation CAUTION Safety switches must not be bypassed (bridging of contacts), turned away, removed or otherwise rendered ineffective. ÌÌObserve EN ISO 14119:2013, section 7, for information about reducing the possibilities for bypassing an interlocking device. NOTICE Risk of damage to equipment and malfunctions as a result of incorrect installation. ÌÌSafety switches and actuators must not be used as an end stop.
Operating Instructions Transponder-Coded Safety Switch CTP-AR 10. Electrical connection The following connection options are available: ÌÌSeparate operation ÌÌSeries connection with Y-distributors from EUCHNER (only with M12 plug connector) ÌÌSeries connection, e.g. with wiring in the control cabinet ÌÌOperation on an AR evaluation unit (only for CTP Extended). WARNING If there is a mistake, loss of the safety function due to incorrect connection.
Operating Instructions Transponder-Coded Safety Switch CTP-AR 10.1. Notes about Important! ÌÌFor use and operation as per the requirements 1), a power supply with the feature “for use in class 2 circuits” must be used. Alternative solutions must comply with the following requirements: Electrically isolated power supply unit in combination with fuse as per UL248. This fuse should be designed for max. 3.3 A and should be integrated into the 30 V DC voltage section.
Operating Instructions Transponder-Coded Safety Switch CTP-AR 10.4. Requirements for connection cables CAUTION Risk of damage to equipment or malfunctions as a result of incorrect connection cables. ÌÌUse connection components and connection cables from EUCHNER ÌÌOn the usage of other connection components, the requirements in the following table apply. EUCHNER provides no warranty for safe function in case of failure to comply with these requirements.
Operating Instructions Transponder-Coded Safety Switch CTP-AR 10.5. Maximum cable lengths Switch chains are permitted up to a maximum overall cable length of 200 m taking into account the voltage drop as a result of the cable resistance (see table below with example data and case example). lmax =200 m l2 l1 ln un = 24 V -20% umin = 24 V -10% iout SPS PLC 5 x 0,34 mm2 CES-AR # 1 CES-AR # n-1 CTP-AR # n n IFO1A/FO1B (mA) l1 (m) Max.
Operating Instructions Transponder-Coded Safety Switch CTP-AR 10.5.1. Determining cable lengths using the example table Example: six switches are to be used in series. Cabling with a length of 40 m is routed from a safety relay in the control cabinet to the last switch (#6). Cables with a length of 20 m each are connected between the individual CES‑AR/CTP‑L1‑… safety switches. l = 140 m l2 = 5 x 20 m l1 = 40 m ln = 20 m un = min.
