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 power.

Diagnostic LED

Models AP1080-2000
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:

 Selectable Failsafe/Latching Operation

 Selectable 120/240VAC Input Power

(9 to 30 VDC Available)

In failsafe operation, the relay is energized when the process is
below the HI setpoint or above the LO setpoint (opposite for non­failsafe). In the failsafe mode, the relays go to the tripped
condition when the power fails.

Dynamic Deadband

The input must remain beyond the setpoint for 100 milliseconds,
uninterrupted, to qualify as a valid trip condition. Likewise, the

input must fall outside the deadband and remain there for 100
milliseconds to return the alarm to an untripped condition. This
effectively results in a “dynamic deadband” - based on time -in
addition to the normal deadband.

Options

U Urethane coating of internal circuitry for protection

from corrosive atmospheres.

P Top mounted, ten-turn dial(s) for setpoint adjustment.

C620 Factory calibration of input range, set points and output

relays. Not available with option P.

AP1080 Single Trip (DPDT, 5A)
AP1090 Single/Dual Trip (2 SPDT, 5A)

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 fail-safe 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 the LO setpoint.

Configuration

The factory presets models AP1080 and AP1090 as follows:

AP1080

Input 0-20mA 0-20mA
Output Single, DPDT Dual, SPDT

Trip HI A: HI, B: LO
Latching No No
Failsafe Yes No
Deadband 0.25% A/B: 0.25%

Power 120VAC 120VAC

For other I/O ranges, remove the four base screws and case to
access the configuration switches.

Replace the cover before applying power.

Refer to Figure 5 for switch locations.

Relay Protection and EMI Suppression

When switching inductive loads, maximum relay life and transient
EMI suppression is achieved using external protection (see Figures
2 & 3). Place all protection devices directly across the load and
minimize all lead lengths. For AC inductive loads, place a properly­rated MOV across the load in parallel with a series RC snubber. Use
a 0.01 to 0.1mF pulse film capacitor (foil polypropylene recom­mended) of sufficient voltage, and a 47ohm, 1/2W carbon resistor.
For DC inductive loads, place a diode across the load (PRV > DC
supply, 1N4006 recommended) with (+) to cathode and (-) to
anode (the RC snubber is an optional enhancement).

Note: A bipolar span selection will double any span from Table 1

(e.g., 10V unipolar span =

10V bipolar span)

3. Using Table 1, configure positions 1 through 4 of the Input
Range Selector for the desired maximum setpoint input. Round
desired maximum input values to the next highest range (e.g., 0­120V = 200V range).

Output

Configure the Mode Selector for the required function. See Figure 6.

Power

Configure the AC jumpers for either 120 or 240 VAC operation.
See Figure 4.

Calibration

Note: To maximize thermal stability, final calibration should be
performed in the operating installation, allowing approximately 1­2 hours for warmup and thermal equilibrium of the system.

Setpoint: Set deadband at its minimum (factory default - 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.

Table 1: AP1080-2000 and 1090-2000

Input Ranges

Deadband: Set deadband to its minimum (factory default - fully

CCW). 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.

Note that Custom Calibration (option C620) is available from the
factory (settings MUST be within specifications):

a) Setpoint A: Type (HI/LO); Units (mA, mV, V); Deadband (%)

*Note: Use Jumper (W2) to configure either voltage or current input.

All unipolar input ranges are zero based.
