Electronic Time Cycle Controller System (ETCC)
Reference: SKI4682P21/07 8/3/2020, Location: Asia
Category: Monitoring & Control
Scope of Work
The company announces its need for supply of Electronic Time Cycle Controller System (ETCC).
Programmable Electronic Time Cycle Controller, designed to control diaphragm operated motor valves in the gas line. The controller should be intrinsically safe, suitable for use in Gas Group IIA&IIB and Zone 1 & Zone 2 hazardous area.
• Display: LCD display in hours, minutes, & seconds.
• ON time: Adjustable between 1 second to 99 hours, 59 minutes, 59 seconds.
• OFF time: Adjustable between 1 second to 99 hours, 59 minutes, 59 seconds.
• The PCB is epoxy coated and usable in high humidity & corrosive environment.
• Pneumatic supply pressure to actuate the motor valve is 15-50 psig.
• Keys: ON TIME, OFF TIME, OPEN VALVE, CLOSE VALVE.
• Supply Input-Output piping: 1/4 inch NPT
• Power supply: 6V rechargeable battery, 12 AH
• Low battery indication shall be provided.
• Enclosure: The controller shall be intrinsically safe and housed in a metal enclosure which shall be weather proof conforming to IP55 or better.
• Supply and output pressure gauges shall be provided.
• The controller is not bleed type: the supply pressure will not bleed off continuously in the controller when the motor valve is in closed position.
• Door safety lock for enclosure.
• Battery charger: 220VAC, 50Hz for 6V rechargeable battery.
DRIP CHAMBERS
Suitable size to arrest moisture and condensate from supply gas with 1500 psi working pressure, complete with inlet, outlet and drain connections, valves and requisite tubing 1/4 inch NPT connections. The pressure regulation has to be done into two (2) stages:
HIGH PRESSURE REGULATOR
The high Pressure regulator (Make: FISHER/SWAGELOK/PARKER/KIMRAY only)
is required to reduce the high line pressure to 100 psig as stated below with requisite pressure gauge, drain connection, tubing and fittings up to low pressure regulator.
Maximum Inlet Pressure: 3000 PSIG
Working Inlet Pressure: 1500 PSIG
Outlet Pressure: 100 PSIG
Inlet & Outlet connections: 1/4 inch NPT
LOW PRESSURE REGULATOR
The low Pressure regulator as stated below with requisite pressure gauge, drain connection, tubing and fittings up to Motor Valve.
Maximum Inlet Pressure: 150 PSIG
Working Inlet Pressure: 100 PSIG
Outlet Pressure: 15-40 PSIG
Inlet & Outlet connections: 1/4 inch NPT
MOTOR VALVE
Diaphragm operated, to suit above items complete with 1/4 inch NPT threaded needle valve, 1500 psi working pressure.
Size: 2 inch nominal
Body: Straight
End connection: 2 inch API LP (F)
Working pressure: 2000 psi
Trim: 19 mm at SS
Actuating pressure: 30 psi (minimum)
Connection for diaphragm pressure: 1/4 inch NPT (F) from ETCC
Type: Normally closed (Pressure to open)
All the interconnection tubing, fitting, isolation and drain valves should be associated with one ETCC."
