Safety Instructions

Qualified Personnel

• The personnel entrusted with installing, operating and maintaining the flow switches have to be suitably qualified; the required knowledge can be gained via training courses or appropriate on-the-job instruction.
• The personnel have to be familiar with the contents of these instructions, which have to be available to them at all times.
• The electrical connection should only be carried out by a fully qualified electrician.
• All work has to be carried out by existing national regulations on accident prevention and safety at work and with any internal regulations of the operator, even if they are not specified in these instructions.
• Always read these operating instructions carefully before installing the new product. Always adhere to the instructions contained herein, especially the safety instructions, otherwise, there is a potential risk of personal injury and damage to instruments and plants.
• Even though we assist with personal consultation or the respective literature, it is the responsibility of the customers to determine the suitability of the product for the specific application.
• The flow switches are state-of-the-art devices. This concerns switching point accuracy, functioning and safe operation of the device.
• However, the professional and safety-conscious conduct of the operator is required to ensure safe operation.

Special Safety Instructions

• The operational safety of the supplied equipment is only guaranteed if it is operated according to its intended use. The specified limit values (see the chapter entitled “Technical data“) should never be exceeded.
• To avoid damage to the flow switch and the monitored system, only use flow switches for minimum or maximum monitoring of the the flow of liquids.
• Always follow and adhere to the flow switch installation instructions.
• Never operate the flow switch in systems that have a greater flow rate than the specified max. flow rate (see the chapter entitled
• “Technical data”, details of the max. flow rate). Otherwise, it will cause irreparable damage to the flow switch.
• Before flow switch installation, ensure that all the materials of the flow switch are chemically and mechanically resistant to the medium which is to be monitored and to all external factors.
• Ensure that the medium is free from magnetic particles.
• Suitable measures should be taken to prevent the medium from freezing. If the flow switch is to be used in ambient temperatures of < 39.2 °F, do not carry out any operation beforehand with pure water, e.g. a test run. Residual water in the flow switch can result in frost damage.
• No greases, oils etc. should be used during the installation of the FES Series devices due to the material resistance.
• Ensure that the max. specified operating pressure is not exceeded.
• Never remove a flow switch or its upper parts from a pipe system under pressure.

If the medium that is to be monitored is very hot, the flow switches or their connection fittings will also become very hot. In this case, neither touch the flow switch nor place any heat-sensitive objects in its vicinity. Protect the flow switch against external magnetic fields in the immediate vicinity, since these can impair device functioning. The technical data of special versions (customised versions) can deviate from the details in these instructions. Please observe the details on the type plate.

Caution: Danger of death due to high voltages! Always de-energize the system before connecting the connector cable. It is prohibited to remove or make type plates or any other information attached to the equipment indecipherable, otherwise, all warranties and the responsibility of the manufacturer no longer apply. Ensure that the maximum electrical contact load specified on the type plate is never exceeded; otherwise, the reed contacts integrated into the switching unit will be damaged. The switching capacity is reduced with inductive loads. Details of the protective circuit can be requested from the manufacturer.

Technological Progress

The manufacturer reserves the right to revise, alter, or modify the flow meter to the most current technology without special prior notice. Further information about the latest updates and potential additions to these operating instructions is available from www.iconprocon.com

Functional Principle
The flow switch consists of a paddle system (1) which has a permanent magnet (2) located at its upper end. A reed contact (3) is positioned outside the flow above this magnet. A second, magnet (4) with opposite polarity is used to create a reset force. The paddle system is moved once it comes into contact with the flow which is to be monitored. The magnet (2) changes its position about the reed contact (3). The contact opens/closes depending on the contact type. As soon as the flow is interrupted, the paddle returns to its original position and the reed contact opens/closes depending on the contact type.

Installation

General Installation Instructions

• When choosing the installation site, ensure that the specified limit values (see “Technical Specifications”) are not exceeded.
• Select suitable measures to prevent the medium from freezing.
• If the flow switch is to be used in ambient temperatures of < 39.2 °F, do not carry out any operation beforehand with pure water, e.g. a test run. Residual water in the flow switch can result in frost damage.
• Firstly, clean the pipe system in which the flow switch is to be installed and remove any magnetic particles, e.g. welding residue.
• The straight in- and outlet pipe (in front of and behind the flow switch) has to be at least 5 x ID.
• The nominal installation position of the flow switch is an “upright standing position” in horizontal pipework.
• The switches should only be installed in a vertical position, deviation max. 45 (Fig. 1).
• Please contact the manufacturer if other installation positions are desired.
• Please make sure that there are no external magnetic fields near the flow switch since these can impair device functioning (Fig. 2).
• There is an arrow on the flow switch. Ensure that this arrow is parallel with the pipe shaft and is facing in the direction of flow during installation (Fig. 2).
• The brass and Plastic union nuts ¾” BSP has a tightening torque of 18.439 … 22.127 ft-lb.
• The plastic union nuts have a tightening torque of 5.163 … 5.901 ft-lb
• During flow switch installation, ensure that the paddle does not touch the wall of the pipe.
• Carry out the installation of your device type as described in the table below.

Electrical Connection

The danger of death due to electrical voltage! Work on electrical installations may only be carried out by qualified electricians or by instructed persons working under the guidance and supervision of a qualified electrician, by the electrical regulations. Always de-energize the system before connecting the wires of the main cable.
CAUTION: Ensure that the maximum electrical contact load specified on the type plate is never exceeded; otherwise the reed contact integrated into the switching unit will be damaged. Inductive loads impair switching capacity. Please ask the manufacturer for information on protective circuits.

Elbow Plug Connector

• Loosen the central screw (pos. 1) and disconnect the junction box (pos. 2) from the connector (pos. 3), Fig. 1.
• Use a screwdriver or similar tool to press out the core (pos. 4) of the junction box (Fig. 2).
• Loosen the screw Cable Gland (pos. 5) Fig. 3.
• Feed the connecting cable into the junction box via the screw connection (pos. 5), the clamping ring (pos.6) and the rubber insert (pos. 7) and subsequently, connect the wires as displayed in the connection diagram (see Fig. 4).
• Press the core (pos. 4) until it locks into position in the junction box (pos. 2).
• Tighten the cable gland (pos. 5).
• Place the junction box (pos. 2) on the connector (pos. 3) and retighten the central screw (pos.1).
• To guarantee the protection class IP 65 per EN 60529, the applied connecting cable has to have a sheathing diameter of between 4.5 and 7 mm.
• Furthermore, ensure that all the connector seals (pos. 2, 3 and 7) have been correctly inserted.
• To adjust the switching unit, open the cover of the switching head Subsequently, loosen the locking screw (2.5 hexagon socket screw) and position the switching unit until the red or white arrow is visible at the entry of the switching contact guide for a desired make contact or break contact respectively.
• You can use the arrow length to make fine adjustments to the switching point: Adjusting to the arrowhead means the switching point is at a lower flow rate. Adjust to the arrow end: The switching point is at a higher flow rate.

Adjust Switching Unit

Standard Contact
The switching unit of the control switch enables 2 contact types: Make contact (normally open): “RED” arrow on the switching unit Break contact (normally closed): “WHITE” arrow on the switching unit.

• Unless otherwise agreed to with the customer, the switching unit is factory set to make contact, i.e. opens if the set switching point is exceeded.
• Carefully retighten the locking screw. We recommend you use a lacquer/thread locker to secure the locking screw of the switching unit after carrying out individual adjustments.
• Close the cover until it locks into place.
• The switching unit does not need to be adjusted when the customer requests a factory-set switching point
