Product Description
AP1080/1090 Field Configurable Limit Alarms
AP1080/1090 Field Configurable Limit Alarms Action Pak models AP1080 single setpoint and AP1090 dual setpoint limit alarms offer flexible, wide-ranging DC input capability. Voltage spans from 10mV to 200 volts and current spans from 1mA to 100mA can be field configured. Bipolar inputs are also accepted. Both models offer configurable latching, failsafe and HI/LO operation. The AP1080 and AP1090 also include 0.25%-50% adjustable deadbands and selectable 120/240VAC operation.
Diagnostic LED
Models AP1080-2000 and AP1090-2000 are equipped with dual function diagnostic LED. The green center LED indicates line power and input signal status. Active line power is indicated by an illuminated LED. If the center LED is off, check line power and the wiring connection. If the input signal is above 100% full scale, the LED will flash at approximately 8Hz. Below 0%, the flash rate is approximately 4Hz.
Operation
The field configurable AP1080 and AP1090 limit alarm setpoints can be configured for HI, LO, latching or failsafe trip operation. Non-latching HI and LO setpoints have respective HI and LO deadbands. In a tripped condition, the setpoint is exceeded and the appropriate red LED will illuminate. The trip will reset only when the process falls below the HI deadband or rise above the LO deadband. To reset a latched setpoint the signal must be in the safe region and the line power turned off for at least 5 seconds. For proper deadband operation, a HI setpoint must always be set above a Lo setpoint.
Calibration
Note: To maximize thermal stability, final calibration should be performed in the operating installation, allowing approximately 1 – 2 hours for warmup and thermal equilibrium of the system.
Setpoint: Set deadband at its minimum (about 20 turns Counter Clockwise) before adjusting the setpoint. With the specified trip voltage or current input applied, adjust setpoint until the relay trips. For HI trip calibration, start with the setpoint above the desired trip. For LO trip calibration, start below the desired trip.
Deadband: Set deadband to its minimum (about 20 turns Counter Clockwise). Set setpoint to desired trip. Adjust voltage/current input until relay trips. Readjust deadband to 50% (20 turns CW). Set voltage/current input to desired deadband position. Slowly adjust deadband until relay untrips.
