Pneumatic Rest Module Instructions For 51.020.35.00 + ATEX Variant Output Connection Diagram Pneumatic Reset Module Instructions Continued Reset Module Technical Data Smooth functionality and reliable timing can only be guaranteed if the instructions within this document are strictly followed. 12 2 Pressure range: Pick-up pressure: Drop-out pressure: 2 to 6 bar 1.2 +/- 0.4 bar 0.3 +/- 0.2 bar Min. 30ms Min. 200 ms 5 million cycles IP40 when connected. IP55 when using a polycarbonate transparent cover. Housing: Plastic material Max. 2 Note: Settings outside the permissible range could cause malfunction.
Automatic reset modules are used alongside ON delay timers to create continuous pneumatic pulsed output signals from 0.2 to 2 seconds. The ON delay timer (timing element) separates these pulsed output signals for automatic repeat timed intervals. ON Delay Timer 1 Pulse length: t 2 Input Reset time: Service Life: Min. 0.2 The pneumatic reset module is set by adjusting the front rotary knob. Please note that the preset roll display has no incremented markings, only a wedge-shaped mark on the roll display and for this reason, the setting point cannot be exactly defined. Timing Element 1 IP rating:
Automatic reset timers generate output signals that repeat while air is connected as shown in the connection diagram above. Removal of air at the input, as shown in the connection diagram, resets the timing element and the reset module. Reset Module Product Selection Installation & Mounting Reset modules can be built into the front panel of equipment. Panel cut-out: 45mm (+0.6) x 22.2mm (+0.3) and secured in place with a fixing clip. Please ensure the panel cut-out is large enough that the reset module is not placed under mechanical tension or strain when built in. Additionally, a panel frame, part number 1499512, provides a wider aperture giving a professional looking finish to panels.
Panel frames are used individually or with protective covers. ON Delay Timer Product Selection - Timing Element Reset Modules are provided with threaded M5 connections. Please ensure a tight seal is provided by fully inserting tubing and by tightening threads sufficiently providing a proper seal. We recommend the use of self-sealing fittings, this is a fitting that incorporates an NBR sealing ring. We do not recommend the use of thread sealing compounds. Due to the close proximity of ports we recommend a cylindrical shape fitting.
Pneumatic Connections Accessories Timing Reset 50010N-04-05 M5 to 4mm o/d tube 50010N-06-05 M5 to 6mm o/d tube Automatic reset by air removal to the reset module (input port 1) when following the connection diagram. Air supply to the to the timing element is interrupted by pulling the rotary knob on the reset module. This resets the timing element to its initial value. ATEX Not suitable for external or harsh environments. Protect from corrosion. General advice is to house within an enclosure or control panel with suitable protection rating or use a protective cover. See accessories.
Environment As well as standard timing devices which are intrinsically safe, we offer ATEX fully certified, CE-marked pneumatic timing products that comply with the ATEX directives for use within category M2 and group II, zones 1 and 21. See product selection. ATEX reset module product (57.020.35.EX) conforms to the following standards: Air Quality Clean, dry and oil free air to instrument quality standards. Please note that at low operating/ambient temperatures air filters alone will not be sufficient. Air dryers are recommended to achieve low moisture dew point. Exhaust Compressed air will exhaust from this device as part of the operating sequence.
This could be sufficient volume and pressure to create risk or introduce problems within an enclosure. Our declaration of conformity can be downloaded from https://www.impulseautomation.co.uk/downloads Safety & Warnings Warning: ATEX products should never be used in Zone 0 or Zone 20, as defined in IEC 60079-10-1:2015 and IEC 60079-10-2:2015. Only competent qualified persons should install, mount, attach hoses, initially operate, maintain, test and disassemble this product. Never disconnect power lines or service the device when the system is powered. This product should only be used for its intended purpose and within the limits and conditions as described.
When cleaning or servicing the product, to avoid electrostatic discharges, use a damp anti-static cloth. The system builder is responsible for ensuring that the final system meets any hazardous zone, EX or ATEX requirements.
