Pneumatic Digital Timer Instructions Pneumatic Digital Timer Instructions Continued For 5 3.K21.03.00/53.K22.03.00/53.K52.05.00/53.K54.05.00/53.K65.05.10/53.K66.05.10 + ATEX Variants Technical Data Smooth functionality and reliable timing can only be guaranteed if the instructions within this document are strictly followed. 2 to 6 bar 999 or 99999 seconds or minutes. Resolution 1/s or 1/m. 1.8 bar minimum input port X. No pressure on port Y [manual pneumatic reset option only]. Timing/frequency error: Max. 15% first count pulse. 1/s 2% or 1/min 0.5%. Reset pulse length: Reset interval: Reset frequency: IP rating: Pressure range: Timing range: Timing input:

Pneumatic pulses are generated and registered on a two-line mechanical display every second or minute. The upper row displays the time elapsed, and the preset value is continuously visible on the lower row. Pneumatic digital timers are used mainly for industrial machine applications where timing is an essential requirement of a process and used for long periods of cumulative timing when the retention of timing information is necessary. Digital timers retain the last timed value upon loss of air. They are also commonly used in areas where no electrical power is permitted or considered dangerous. Input port Y - 180 ms minimum. No pressure on port X [manual pneumatic reset option only].

50 ms before next timing input port X [manual pneumatic reset option only]. One reset per two seconds maximum. IP40 when connected. IP55 when using a polycarbonate transparent cover. Mechanical life: Display: Reset: Housing: There are two options:  Manual pneumatic reset: The timer starts from zero and times up to a preset value. Input P (mains pressure input) and output A (A connects to P on reaching the pre-set value). Output A is continuous until reset. Time elapsed on the upper row will continue to increment while air is connected to the timing element (port X) until reset. 30 x 10⁶ 3 or 5 digits (dual line display). (W) 4mm or 3mm x (H) 4mm respectively, white on black background.

Manual button reset with pneumatic reset to port Y [manual pneumatic reset option only]. Plastic material.  Manual automatic reset: The timer starts from zero and times up to a preset value. Input P (mains pressure input) and output A (A connects to P on reaching the pre-set value). A single pulsed output (port A) of approximately 300ms to 340ms is generated. Time elapsed on the upper row resets automatically. The process repeats while air is connected to the timing element (port X). Product S election To set the preset values, push down the white lever and increment the display by pushing the adjacent black buttons.

Pneumatic digital timers are intended to be built into the front panel of equipment. Panel cut-out: 52mm x 52mm. Distance between holes: 63mm and fastened with two countersunk M4 screws provided. Please ensure that the panel cut-out is large enough that the timer is not placed under mechanical tension or strain when built in. A rear mounted metal supporting bracket is provided with the timer. Installation & Mounting Pneumatic Connections Digital timers are provided with threaded M5 connections.

Input X (input for timing), input Y (input for the reset pulse) [blanked for manual automatic reset option] , input P (mains pressure input) and output A (A connects to P on reaching the pre-set value). 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. Accessories Reset On reaching a pre-set value, ports A and P are connected - see manual pneumatic reset and manual automatic reset options.

ATEX To close pressure to port A and reset the device, press the front reset button or provide a pulse signal to port Y [manual pneumatic reset option only] . Pressure must be removed from the timing input (port X) completely before resetting to avoid jamming, mistiming or irreparable damage to the device. Note: Output A cannot be used to reset the device at reset port Y. As well as standard counting devices which are intrinsically safe, we offer ATEX fully certified, CE-marked pneumatic counting products that comply with the ATEX directives for use within category M2 and group II, zones 1 and 21. See product selection.

Environment ATEX counting products (57.K21.03.00.EX, 57.K22.03.00.EX, 57.K52.05.00.EX, 57.K54.05.00.EX, 57.K65.05.10.EX, 57.K66.05.10.EX) conform to the following standards: 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. 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. 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. Exhaust 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.
