KS98-2 Multi-Function Controller: Hot Water & Steam Boiler Control System from Gems Sensors & Controls
Gems KS98-2 Multi-Function Controller
The selection process for incorporating electronic controls into a boiler system can be daunting and can vary depending on the application. For the simplest of applications, a basic safety relay may be all that is needed. For more complex applications, feature rich controllers that can assist the end user in troubleshooting the heating system are a necessity. No matter what your application, specifying and designing in a controller that meets local and federal regulations is a must.
Application
Industrial and commercial boilers are expected to operate uninterrupted at peak efficiency. Anything less can result in serious waste, and ultimately, money lost. Configuring intricate boiler controls with many control loops to fit ever-changing heat requirements can be challenging without the right modern controller. Sophisticated, accurate, and repeatable boiler control provides an effective solution to reduce waste, improve efficiency, increase safety, and lower cost.

Application Solution:
Gems KS98-2 multi-function controller – The KS98-2 combines PID control, process monitoring, sequence control, data logging and alarm monitoring functions in a compact programmable unit. It can act as a dedicated DDC (direct digital controller) for a single boiler or can include many devices in a primary/secondary configured DCS (distributed control system) for multiple boiler control. With fully modular internal I/O, optional remote I/O, and up to 30 control loops, the Gems KS98-2 can be tailored to monitor and control the many process control loops required in a sophisticated boiler system. The comprehensive function block programming library supports many features for customizable user interface and complete process control.
Supported control and monitoring functions for Gems KS98-2 multi-function controller include:
- Pressure control loops may be used for the control of boiler pressure or fuel oil pressure.
- Temperature control loops may be used for the control of steam or water temperature from boilers or fuel oil temperature from fuel oil heaters.
- Liquid level control loops may be used for the control of boiler tank water level. Supports one, two, or three element feed water control.
- Flow control loops may be used for the control of fuel flow into the boiler burners, burner draft airflow, feed water into a boiler, or steam flow out of a boiler.
- Fully metered Combustion controls to automatically provide the proper fuel to air ratio over the entire boiler operating range.
Features and benefits optimized for boiler control:
| Recorder with data-logging/event logging | Trend curves |
| Programmed safety interlocks | Sequence control |
| Alarm indication | Cascade control |
| Totalizer/math functions | Precise ratio control |
| Customizable touch screen HMI | Manual control with password protection |
