Technical data

¹⁾ Each solenoid is required to be equipped with a short-circuit protection fuse that corresponds to its rated current (pursuant to DIN 41571 or IEC 60127-2-1, see technical data) or else is required to be equipped with an upstream installed motor protection circuit breaker with short-circuit and thermal instantaneous tripping (set to rated current). This fuse may be either housed in the associated supply unit or otherwise has to be installed upstream. The fuse rated voltage is required to be equal to or greater than the specified rated voltage of the solenoid. The breaking capacity of the fuse is required to be equal to or greater than the maximum expected short circuit current at the place of installation (usually 1500 A).

For 14F52:
Connecting cables and connecting lines shall be suitable for permanent application in a temperature range of – 40°C up to + 105°C. When using silicone or silicone-containing cables for connection or cables which are not scratch-proof, these shall be protected against mechanical damage.
The armature tube should be subjected to a routine test with 1.5 fold the nominal operating pressure.

Warranty

A trouble-free operation of the solenoid coil can only be warranted, if the key data entailed in the chapter "Technical data" is adhered to and the conditions specified in the chapter "Operating conditions" are fulfilled.

Operating Conditions

Power supply

Harmonics do not affect the function, insofar as the effective (rms) value of the sum of all voltages is within the tolerance specified for the rated voltage. The allowable values are in the case of power interruption or voltage drop, dependent on the valve and have thus to be procured from the manufacturer.

Enhanced requirements

Please coordinate the operation and ambient conditions with ionizing and non-ionizing radiation, vibration, shock, shock duration and aggressive ambient media, with the manufacturer.

Electromagnetic compatibility

• The solenoids are not sensitive to radiated disturbances according to EN 61000-6-3.
• The solenoids do not emit any radiated disturbances according to EN 61000-6-2.
• In the case of conducted disturbances, the information on the power supply has to followed.

Assembly / Dismantling

Before starting, the chapters entitled „Safety" and „General Safety Warnings" must be read and fully understood.

Assembly

In the case of types 14A80 / 14C80, first slide the O-ring followed by the solenoid, onto the guide tube of the valve. In the case of type 14F52, the supplied O-ring is required to be inserted into the groove opposite the cable entry side, before the solenoid is slide onto the guide tube. Insert the sealing disc on the guide tube and fasten it with the securing element.

Connection work

In the case of the battery installation, the centre spacing from device-to-device is required to at least amount to 55 mm, in the case of the type 14F52. For types 14A80 and 14C80, no space therebetween is required. The connection cable that is integrated on the solenoid is required to be connected either to operating equipment in a non-hazardous area, or else to operating equipment that is approved for the relevant hazardous area, whereby the polarity is arbitrary. The cable is required to be firmly laid, whereby a corresponding strain relief has be ensured. Prevent sharp bends of connection cable and strands, in order to prevent short circuits and interruptions. Prior to commissioning, it has to be ensured that the connected circuit is protected with the fuse specified in the "Technical data". The solenoid may only be turned on, if it is mounted on a valve body.

Disassembly

The dismantling of the connection cable has to be performed in compliance with the general safety warnings. Loosen the securing element and remove solenoid and O-ring from the guide tube.

Disposal

To ensure explosion protection, the solenoids should not be repaired. They should be disposed directly as special waste or returned to the manufacturer.

Safety

Intended use

The solenoid are used to actuate the valves of the Eugen Seitz AG. The respective valves that are suitable for the solenoid, are required in each to be selected by the manufacturer or one of his representatives.

Pursuant to the EC-type examination certificate PTB 05 ATEX 2050X for models 14A80 and 14C80 as well as PTB 12 ATEX 2024X and IECEx PTB 20.0011X for model 14F52, the solenoids are approved in the assembled state as devices of category 2 and the device group II, and are therefore suitable for use in areas with potentially explosive gas-, vapour- and mist-air mixtures of the zones 1 and 2 as well as dustair mixtures of zones 21 and 22.

Authorised personnel

The work described herein may only be performed by authorised personnel. Authorised personnel are individuals who have received "electro-technical instruction" (EN 60204-1).

About this operating instructions manual

These instructions are a constituent part of the product and are therefore required to be integrated into the relevant operating manuals of the plant or machine descriptions.

General Safety Warnings

Prior to the start of the connection work and disassembly, ensure that the operating voltage is switched off and secured against unauthorised reconnection.

The housing of the solenoid can be hot. Touching the housing poses a risk of burns.

For the purpose of the maintenance of explosion protection, it is absolutely necessarily that the installation instructions are complied. Any alterations to the solenoids and improper use are forbidden. The solenoids of the type 14F52, are required to be installed in a manner that does not expose them to impact.
