SAFETY INSTRUCTIONS FOR INSTALLATIONS IN DANGEROUS ZONES
The HMX and HWX series Melt pressure transmitter must be installed and serviced in conformity to plant engineering and maintenance standards for environments classified at risk of explosion due to the presence of gases (example: EN 60079-14, EN 60079-17 or other national standards) and dust. Please avoid any dust accumulation on the transmitter. The HMX and HWX series Melt pressure transmitter must be connected to other equipment (galvanic isolation barriers) with individual ATEX certification such as [Ex ia Ga] IIC having the following characteristics:
- maximum voltage Uo = 30V
- maximum current Io = 100mA
- maximum power Po = 0.75W
MOUNTING INSTRUCTIONS FOR INSTALLATIONS IN DANGEROUS ZONES
Based on the application, HMX and HWX series Melt pressure transmitters must be installed according to the instructions
HMX and HWX series transducers must be powered by means of galvanic isolation barriers with a maximum of 30V The AUTOZERO procedure must be run by means of the transmitters pen by short circuiting the CAL lines as shown in the following figures or by means of HART control. The CAL procedure must be run by short circuiting the leads directly on the cable or on the connecton terminals.
For models HMX2 and HWX2 with temperature measurement, the thermocouple circuit must be powered by means of galvanic isolation barriers with a maximum of 30V. Products of HMX series are designed and available in compliance with Directive 2011/65/EU (RoHS II) only for large-scale stationary installation or industrial tools, or for B-to-B laboratory equipments for R&D purposes.
