2 INTRODUCTION The is a logic module that permits switching on a load when certain other circuits are energized. Complete isolation between circuits is maintained. Two separate logic modes are available and programmed by switches on the circuit board. Logic: In this mode an output is obtained when there is an input at INPUT and INPUT 2 and INPUT 3. All three inputs must be present in order to obtain an output Logic: In this mode an output is obtained when there is an input at INPUT or INPUT 2 or INPUT 3. Any input present will create an output. Input Signal Polarity: An input signal polarity selector switch permits operating with inputs that are either a +2 volt or they may be a connection to ground. Output Signal Polarity: An output signal polarity selector switch permits selecting whether the output should be +2 volts or a connection to ground. CAUTION The output load, either +2 volts or ground Must not exceed 2 amperes

3 INSTALLATION Mount the logic module in a dry location away from any sources of heat. Figure illustrates the wiring required. The +2 volts and Ground input are required to supply the output of the logic module. Note that the input signal may be either a +2 volts or Ground. The polarity of the input signal is independent of the polarity of the output. A separate selector switch is provided to select the polarity of the output. NOTE: DO NOT EXCEED AN OUTPUT LOAD OF 2 AMPERES.
