FAQs of Single Set with Band type Alarm pH Controller:
Q: How do I set and adjust the single set point with band on this pH controller?
A: You can set and adjust the single set point with band using the front panel controls. By selecting your target pH value and defining the allowable band range, the controller monitors the process and triggers the alarm relay output if the pH moves outside the set limits.
Q: What is the process for connecting sensors and power supply to the controller?
A: The controller uses screw terminal connections for secure and straightforward wiring. Connect your pH sensor to the appropriate input terminals and connect 220V AC power as per the manual. Always ensure power is off during installation for safety.
Q: When does the band alarm activate, and how does it function?
A: The band alarm triggers when the monitored pH value deviates from your set point by more than the specified band limit. A separate relay contact is activated, which can be connected to audible, visual, or remote alarm systems for timely notification.
Q: Where should this pH controller be installed for optimal performance?
A: This device is designed for panel mount installation in monitoring rooms, control cabinets, or process plants. Ensure that the panel location is free from excessive heat, moisture, and vibration to maintain long-term accuracy and reliability.
Q: What are the benefits of using this pH controller in industrial applications?
A: This controller ensures precise, automatic pH regulation, reducing manual monitoring needs and minimizing the risk of undesirable process changes. The band-type alarm further enhances safety by providing early alerts, enabling proactive intervention to protect both equipment and product quality.
Q: Can the pH controller withstand harsh environments and high-pressure conditions?
A: Yes, its IP65-rated front panel protects against dust and water ingress, making it suitable for industrial settings. Additionally, it can operate under pressures up to 6 bar, expanding its usability in various challenging environments.
