Analog Output Wiring
Locate the analog output connector on your chamber. Figure 8-13 is a representation of the typical
analog output connection provided on most chambers; however, as changes and/or improvements
are made, your specific connection style may vary. To connect the output signal, first make sure that
the output type is set correctly on the EZT-570S as described above.
It is recommended that a quality, twisted-pair shielded cable, is used to connect the output signal to
your device. Make sure to observe proper polarity when connecting the signal leads. Only connect
the drain wire of the shielded cable at your device, 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 8-13 Analog Output Wiring
If you connect more than one device to each output make sure that you do not exceed the output
capabilities of the EZT-570S. Note that the provided connection may have terminals for all four
available outputs; however, your chamber may be equipped with only one based on purchased
options. If you are having trouble with getting an output to operate, first make sure that it is available
on your chamber.
Exceeding the recommended load impedance for the output will cause signal
degradation and may damage the output. Use care when connecting remote devices
and make sure they stay within output capability. Configure the EZT-570S’s output for
the desired signal level and cycle power prior to connecting the load device.
