Model No.: CEMS-1-RM-0223
It is a well-known fact that friction created by any means will generate “Static Charges”. These charges if not dissipated to earth will result in Static Charges accumulation and subsequent Electro Static Discharge. The ESD may cause Fire and Explosions.
In Pharma & Chemical units, equipment such as Reactors, Centrifuges,Driers, Shifters, etc., are used continuously for 24 Hrs. in a day to manufacture different products. During the running of the above equipment, Static Charges are developed due to friction. All the equipment’s are to be earthed by means of earthing strips. Since equipment’s are running 24 hrs, the earth connections need to be healthy 24/7 to dissipate the Static Charges developed.
The duty of checking earth continuity of the equipment is normally assigned to the electrical department. Due to limited manpower in the department, monitoring earth connections on daily basis is not practicable. The Earth connections are usually checked once in 3 months or 6 months. Any loose contacts are defects in earth connections goes unnoticed during these intervals.
Why less than 10.0 Ohms threshold? As per IS/IEC 60079-0: 2017 &
IS/IEC 60079-11:2011 metallic items in good contact with the earth should have a resistance to it of less than 10.0 Ohms. Although a value of up to 1.0 M Ohms is acceptable for static dissipation values above 10.0 Ohms may give an early indication of developing problems (e.g. corrosion or loose connection).
Mr. P.V.Vidyadhara Rao (Proprietor) is an ESD Trainer and Certified ESD Auditor. During the ESD Audits, he noticed a safety gap in equipment earth connection monitoring and envisaged a need for a continuous earth monitoring system to fill this safety gap. Based on his findings and recommendations our Technical Team has designed and developed a continuous earth monitoring system CEMS-1-RM-0223 to fill the gap and reduce workload on electrical personnel, and continuity in the safety through the production schedule.
A key function of equipment Earthing is to provide a controlled method to prevent the buildup of static electricity, thus reducing the risk of electrical Discharge in Potentially hazardous environments. The Electrical resistance from the equipment to Earth should be 10.0 Ohms Maximum. This electrical resistance values are to be maintained continuously as per IS: 7689.
The system CEMS-1-RM-0223 monitors resistance value to Earth and any fault will be indicated by a RED LED and Audio Signal. The system monitors equipment connected continuously. The system draws the attention of the personnel to take remedial action should a fault arise in equipment earthing. (Red LED light up and Aural Bip sound together)
CEMS-1-RM-0223 has provision to monitor Single equipment, and comes in a flame-proof enclosure. Equipment to earth loop is measured by intrinsically safe voltage & current. Wiring details given in Schematic Block Diagram.

Caution Note:
Before carrying out any electrical welding works on connected Equipment structures and periferrals during maintenance activities.
Because CEMS-1-RM-0223 unit printed circuit remains connected to earth pit, even if power is switch OFF to unit, branched out welding currents flows through E. loop sensing lead through narrow printed cirucit strips to earth pit, it damges the printed circuit board.
To prevent above damage, remove the two 4 Sq.mm cable coming from earth pit to terminal block in junction box. Remove the two wires, tape the open ends and lay it in free space in junction box. Other earth loop check wires (1.5 Sq.mm wires) are also to be remvoed from their terminals and pulled out of respective glands and hold out side the junction box. Before putting back in service CEMS-1-RM-0223 restore all the 1.5 Sq.mm E. loop wires in their sequence and restore the earth pit wires.

Continuous Earth Monitoring System is designed to Monitor Earthing of Pharma product process equipment. Once installed the system checks single monitoring point.
In the event of equipment earthing fault (resistance more than 10 Ohms), the system detects it and indicates Red color LED along with Audio Signal. At the same time.
