2.3.4 - Voltage Source Connection in mV or V
Either a 0 to 55mVdc or a 0 to 5Vdc voltage must be applied between terminals
2(+) and 3(-) in the case of input 1 and between terminals 5(+) and 6(-) in the case of
input 2. A 0 to 10Vdc voltage must be applied between terminals 1(+) and 3(-) in the
case of input 1 and between terminals 4(+) and 6(-) in the case of input 2. Those
connections are illustrated in figure 7.

Note 1: Keep shielded wire disconnected at this end.
Note 2: Connect shielded wire to power supply ground terminal. If ground terminal non-existent keep shielded wire disconnected at this end.
2.4 - Control and Alarm Output Signal Connection
In their most complete versions the controllers can be provided with up to four
output signals: output 1, output 2, output 3 and output 4. Output 1 can only be used as a
control output. Outputs 2, 3 and 4 can be used as control or alarm outputs, depending on
controllers software configuration established by the user. A maximum of three alarm
outputs can be provided.
