lethal situations. The CE mark proves the compliance of the device with the essential requirements of the directives. Warning This device is designed for connection to hazardous electric voltages. Ignoring this warning can result in severe personal injury or mechanical damage. To avoid the risk of electric shock and fire, the safety instructions of this manual must be observed and the guidelines followed. The specifications must not be exceeded, and the device must only be applied as described in the following. Prior to the commissioning of the device, this manual must be examined carefully. Only qualified personnel (technicians) should install this device. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. WARNING Until the device is fixed, do not connect hazardous voltages to the device. The following operations should only be carried out on a disconnected device and under ESD safe conditions: Troubleshooting the device. Repair of the device must be done by PR electronics A/S only. GENERAL HAZARD- OUS VOLTAGE

50 to 1000 Volt AC. Technicians are qualified persons educated or trained to mount, operate, and also troubleshoot technically correct and in accordance with safety regulations. Operators, being familiar with the contents of this manual, adjust and operate the knobs or potentiometers during normal operation. Receipt and unpacking Unpack the device without damaging it. The packing should always follow the device until this has been permanently mounted. Check at the receipt of the device whether the type corresponds to the one ordered. Environment Avoid direct sunlight, dust, high temperatures, mechanical vibrations and shock, as well as rain and heavy moisture. If necessary, heating in excess of the stated limits for ambient temperatures should be avoided by way of ventilation. All devices fall under Installation Category II, Pollution Degree 1, and Insulation Class II. Mounting Only technicians who are familiar with the technical terms, warnings, and instructions in the manual and who are able to follow these should connect the device. Should there be any doubt as to the correct handling of the device, please contact your local distributor or, alternatively, PR electronics A/S www.prelectronics.com Mounting and connection of the device should comply with national legislation for mounting of electric materials, i.e. wire cross section, protective fuse, and location. Descriptions of Input / Output and supply connections are shown in the block diagram and side label.

The max. size of the protective fuse is 10 A and, together with a power switch, it shall be easily accessible and close to the device.

As manufacturer PR electronics A/S Lerbakken 10 DK-8410 Rønde hereby declares that the following product: Type: 5725 Name: LED frequency / pulse converter is in conformity with the following directives and standards: The EMC Directive 2004/108/EC and later amendments EN 61326-1 : 2006 For specification of the acceptable EMC performance level, refer to the electrical specifications for the device. The Low Voltage Directive 2006/95/EC and later amendments EN 61010-1 : 2001 Rønde, 17 February 2011 Kim Rasmussen Manufacturer’s signature

5725 • Frequencies from 0.001 Hz to 50 kHz • Input for various sensors; NPN, PNP, Contact, Namur, S0, Tacho and TTL • 2 SPDT relays and analogue output • 4-digit, 14-segment easily readable LED display • Universal supply voltage Application • 5725 is a digital indicator for readout of frequency signals and pulse signals. • Typical applications are indication and conversion of process speed measurements and flow rate. • The indicator can also be used for measuring the passing time on e.g. a conveyor line, as the 5725 can handle period time measurements. • Process control is possible as the type 5725D contains 2 pairs of potential- free change-over relays and an analogue output. • The display offers IP65 protection from the front and the splash-proof cover - PR type 8335 - can be used against atmospheres and liquids. Technical characteristics • 4-digit LED indication with 13.8 mm 14-segment characters for a -1999...9999 display readout with programmable decimal point. • Relay ON / OFF indication via front LED’s. • Various input sensor types and custom current and voltage trig levels can be selected via the programming menu. • Input and supply of NPN and PNP proximity switches is possible from the input terminals. • A menu item allows the user to minimise the installation test time for the relay outputs by activating or deactivating each relay independently of the input signal. Mounting / installation • Panel mounted indicator, 48x96mm which obtains IP65 (type 4X) when using the rubber gasket provided. • All standard operational parameters can be adjusted to any application by way of the front function keys. • Help texts in eight different languages are available and can be selected via a menu item.

the function keys Documentation for the routing diagram In general: When configuring the display you are guided through all parameters, allowing you to choose the settings which fit the application. For each menu there is a scrolling help text which is automatically shown in the display if no key has been activated for appr. 5 seconds. Configuration is carried out by way of the 3 function keys 1 2 and 3. 1 will increase the numerical value or choose the next parameter. 2 will decrease the numerical value or choose the previous parameter. 3 will accept the chosen value and go to the next menu. If a function does not exist in the hardware, all parametres belonging to that function will be skipped in order to make configuration as simple as possible. The configuration will not be saved until the end of the menu structure when the display shows - - - -. Pressing and holding 3 will return to the previous menu or go back to the default state (”Monitor”) without saving the changed values or parameters. If no key is activated for 2 minutes, the display will return to the default state (”Monitor”) without saving the changed values or parameters. Furhter explanations: Fast setpoint adjustment and relay test: These menus are interactive and allow you to adjust the setpoints while the display is measuring the input signal. The diodes will then indicate when the relays change state, thus easing the setpoint adjustment in many situations. By activating 1 and 2 simultaneously, a relay test will be initiated and the relay will change state. The setpoint adjustment will be saved by a quick press of 3 . Holding down 3 for more that 0.5 seconds wil return the display to the default state (”Monitor”) without changing the setpoint.

parameters. There are two levels of password protection. Passwords be­tween 0000 and 4999 allow access to the fast setpoint adjustment and relay test menus (using this password blocks access to all other parts of the menu). Passwords between 5000 and 9999 block access to all parts of the menu, fast setpoint and relay test (current setpoint is still shown). Default password 2008 allows access to all configuration menus.
