Analog Input Wiring
Locate the analog input connector on your chamber. Figure 8-11 is a representation of the typical
analog input connection provided on most chambers; however, as changes and/or improvements are
made, your specific connection style may vary. To connect your input signal, first make sure that the
input type is set correctly on the EZT-570S as described above.
Next, using a quality, twisted-pair shielded cable, connect your input signal to the correct input
number. Make sure to observe proper polarity when connecting your signal leads. Only connect the
drain wire of your shielded cable at your signal source, or the chamber, not both. Connecting the
shield to ground at both ends of the cable can induce unwanted “noise” into the signal leads.
Figure 8-11 Analog Input Wiring
Connect only one signal source to each input. Note that the provided connection may have terminals
for all five available inputs; however, your chamber may be equipped with only one based on
purchased options. If you are having trouble with getting an input to operate, first make sure that it is
available on your chamber.
Exceeding maximum allowed overload ratings can cause permanent damage to the
input. Use care when connecting remote signal generators and make sure they cannot
overload the EZT-570S’s inputs.
Configure the EZT-570S’s input for the desired signal level and cycle power prior to
connecting the source signal or damage to the input may result.
