ALTERNATING CONTROLLERS ATC-Diversified Electronics offers a wide variety of models for various staging requirements. The different models available are: Duplexors, Triplexors, Quadraplexors, Special Function, and Expandable Alternating Relays. The Alternating Relay is used in multiple load installations to assure equal run time on all loads. They also allow for the addition of more capacity in the event of excess load requirements.
ARA, ARB Series The Duplexor is used in control panels where two loads are required to alternate to provide equal run time on the loads. The alternating action is initiated by a control switch, which is common with one side of the control voltage. The output contacts will change states each time the control switch is opened, thus alternating the two loads. The LED indicators show the position of the output relay. The ARA Series is the standard Duplexor providing automatic alternating sequence.
ARA Series The Triplexor and Quadraplexor Alternating Relays are designed for use in multiple load installations that are required to alternate in sequence while assuring equal run time on all loads. They also allow for additional loads to run in the event of excess load requirements. The Triplexor and Quadraplexor have the option of automatic alterations or external clocking alterations.

The control switches connected to terminals 3 through 6 are labeled OFF (CS2), LEAD (CS3), LAG (CS4) and ALARM (CS5). Under normal operation the lead load energizes when the off and lead control switches close in order. The lag load energizes when the lag closes and the alarm load energizes when the alarm switch closes.
ARM Series These Triplex and Quadraplex Controllers are available with either Sequence-On-Simultaneous-Off (SOSO) or First-On-First-Off (FOFO) output logic. The special function models are differentiated by a rotary switch that allows any output to be locked as the lead load or any Process one load to be omitted while sequencing only the remaining loads.
ARM Series OPERATION triplex controllers Intrinsically safe equipment and wiring is equipment and wiring which is incapable of releasing sufficient electrical or thermal energy under normal or abnormal conditions to cause ignition of a specific hazardous atmospheric mixture in its most ignitable concentration.
The ARM-120-AGE and ARM-120-AHE Quadraplex Controllers have five switch inputs and four load outputs. The inputs are designated off, lead, lag, 2nd lag, and 3rd lag. With the off switch closed, the loads energize in sequence upon closure of the lead, lag, 2nd lag, and 3rd lag inputs. If the off switch fails to close, the lead load will not energize until both the lead and lag switches close. De-energization of the loads depends on the output logic of the selected controller.

The over-temperature function incorporates a bistable relay that retains its position during power failures. IND. CONT. EQ.
WIRING Figure 1 shows the connections for use with a Flygt model FLS float switch. The leakage sensitivity must be adjusted to 1 k for float switch applications. If a pair of conductive probes is used to sense seal leakage, a 100 k resistor is required as shown in Figure 2, and the sensitivity should be set to the desired value. SPM Series OPERATION SPECIAL CONTROLS The states of the unit’s relay outputs are determined by the series combination resistance of the leakage and temperature sensors.

BFA Series OPERATION With nominal 3-phase line voltage applied, a flashing green NORMAL LED gives positive indication of a good fuse and integrity of the wire connection to each side of the fuse.1 A flashing red FAULT LED gives positive indication of an unconnected or open fuse, or a BFA wiring fault that needs corrected such as a lost connection to either side of the fuse or mismatched line and load wires.2 When phase loss occurs, both FAULT and NORMAL LEDS will extinguish.
A. Normal, fuse good, electrical contact across fuse 2. A. Unconnected or blown fuse B. Bad Connection Load Side (white stripe wire) C. Both of the above A. Phase voltage loss with no motor regeneration B. The above accompanied with an unconnected or blown fuse A. Bad Connection Line Side (solid color wire) B. The above accompanied with an unconnected or blown fuse C. Phase Voltage loss with motor regeneration accompanied with an unconnected or blown fuse A.
GFD Series The ATC Diversified Electronics GFD Series is intended for the use on ungrounded systems to detect and indicate the phase of the first ground fault condition. This enables corrective action to avoid the potential hazards resulting from a second ground fault. OPERATION With nominal 3 phase line voltage applied, a flashing NORMAL green LED gives indication of a non-fault condition and integrity of the wire connection to the corresponding phase.
