Every boiler relies on a few key pressure controls to stay safe and operate efficiently: • Firing Rate Control – Modulates the burner for steady operation. • Operating Pressure Control – Stops and restarts the boiler at set pressures. • High Limit Control – A manual reset backup for added safety. • Low Fire Hold – Keeps the boiler in low fire until safe pressure is reached. Together, these controls keep your boiler running safely and smoothly. | WARE

The relay logic diagram consists of four rungs. Each rung contains various components such as normally open push buttons, relay coils (CR1 and CR2), normally open and normally closed contacts, solenoid coils (Sol 1 and Sol 2), and a 5/3 directional control valve connected to a cylinder. This setup facilitates the control of the cylinder’s movement using two buttons, a valve, and corresponding electrical components. #mechatronics #plcprogramming #programming #programmer #controlsengineering #auto
