Power
Description
The Action Pak model AP1690 dual setpoint limit alarm offers flexible, wide ranging AC input and relay
output capability. Voltage spans from 100mV to 200VAC and current spans from 10mA to 100mA AC
can be field configured. For current input spans of 1 to 5 Amps a 0.1 (0.1%) shunt resistor (Model #C006)
is available. The AP1690 offers configurable latching, failsafe, and HI/LO operation. The unit also includes
0.25% to 50% adjustable deadband and selectable 120/240VAC power.
Diagnostic LED
The Model AP1690 is 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.
Output Selection
The dual setpoint AP1690 provides the following relay outputs:
AP1690
Single/Dual Trip
(2 SPDT, 5A)
Setpoints are top accessed multi-turn potentiometers or option "P" provides top mounted ten-turn clock
face dials.
Operation
The field configurable AP1690 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 non-latching trip will reset only
when the process falls below the HI deadband or rises above the low 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, the HI setpoint must always be set above the 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 trip condition when 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. Figure 1: Limit alarm operation and
effect of deadband.

Refer to Figure 4 for switch locations.
Input
1. Position input jumper W1 for voltage or
current inputs.
2. Using Table 1, set DIP switches S1-S6" and
jumper "W1" for the desired maximum setpoint
input. Round desired maximum input values to the
next highest range (e.g., 0-120V = 200V range).
Output
1. Configure the Mode Selector for the required
function. See Figure 5.

1. Configure the AC jumpers for either 120 or
240VAC operation. See Figure 6.
Calibration
Note: To maximize thermal stability, final cali-
bration should be performed in the operating
Table 1: AP1690 Input Ranges
Table 3: AP1690 Input Jumper Settings
installation, allowing approximately 1-2
hours for warmup and thermal equilib-
rium of the system.
Setpoint: Set deadband at its minimum
(factory default - fully CCW) before ad-
justing the setpoint. With the specified trip
voltage or current input applied, adjust
setpoint until the relay trips. For HI trip
calibration, start below the desired trip.
Deadband: Set deadband to its minimum
(factory default - fully CCW). Set setpoint
to desired trip. Adjust voltage or current
input until relay trips. Readjust deadband to
50% (fully CW). Set voltage or current input
to desired deadband position. Slowly adjust
deadband until relay untrips.

Relay Protection and EMI
Suppression
When switching inductive loads, maximum
relay life and transient EMI suppression is
achieved using external protection (see Figure 2
& 3). Place all protection devices directly across
the load and minimize lead lengths. For AC
inductive loads, place a properly-rated MOV
across the load in parallel with a series RC
snubber. Use a 0.01 to 0.1
µ
F pulse film capaci-
tor (foil polypropylene recommended) of suf-
ficient voltage, and a 47 , 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).
