Description

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 input power.

Diagnostic LED

Models AP1080-2000 and AP1090-2000 are equipped with a 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.

Output Selection

The single setpoint AP1080 and the dual setpoint AP1090 provide the following relay outputs:

AP1080

AP1090

Setpoints are top accessed multi-turn potentiometers or option "P" provides top mounted ten-turn

dials.

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 rises above the

LO deadband (see figure 1). 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.

In failsafe operation, the relay is energized when the process is below the HI setpoint or above the

LO setpoint (opposite for non-failsafe). In the failsafe mode, the relays go to the tripped condition

when the power fails.
