A K8AC digital heater burnout alarm.
[Features]
Outputs highly accurate heater burnout alarms using high resolution digital measurements.
· Can detect a single burnout from among multiple heater circuits. Detects burnout by digitally determining minute current fluctuations.
Uses screwless clamp terminals so less wiring required. (K8AC-H2 series only)
· Uses non-loosening screwless type clamp terminals, reducing the amount of time spent on tasks such as torque control and retorquing for screw fastening operations etc.
· Easy to wire. Simply insert the rod shaped sleeved terminal into the terminal port.
Built-in simple scaling function for setting the external CT ratio and CT number of throughputs. (K8AC-H2 series only)
· Easy scaling settings by simply inputting (1) CT ratio and (2) the number of CT throughputs.
[A two-type series for use with different heater control methods]
· Types with ON/OFF controls, phase controls, and heater burnout alarms for cycle control heaters are available.
Can detect over-current caused by layer short circuits in the heater, and detect SSR faults.
· Not only detects over-current whereby it then produces an alarm warning of heater burnout, but also detects over-current caused by layer short circuits.
· Monitors the heater current and control outputs from the temperature adjuster so it can detect SSR short-circuit faults and SSR open faults.
· Detects SSR faults, enabling the prompt discovery of disabled temperature controls.
Compatible with heater burnout alarms for phase control heaters. (K8AC-HP type)
· Shifts the burnout detection value in line with the control output value from the temperature adjuster.
· For phase control and cycle control, the amount of power output is analog controlled in line with the signal for the current output of the temperature controller (4 to
20mA) .
· The K8AC-H shifts the heater burnout alarm value in line with the control output amount for the temperature controller.
· Through this, it achieves stable heater burnout alarm functionality.
· Compatible with the power adjuster gradient settings.
· When making gradient settings on a power adjuster, make sure to set a gate current level commensurate to the gradient settings.
