If you change the analog output type, change from voltage to current or vice versa, power
must be cycled to the EZT-570S controller in order for the output to switch types.
Reversing Output Operation
For compatibility with external monitoring and control devices, the EZT-570S allows the output signal
generated by the input/loop source selection to be inverted, meaning the minimum output signal, 0V
or 4mA, will be transmitted when the selected loop source is at its maximum value, and the maximum
output signal, 10V or 20mA, will be transmitted when the selected loop source is at its minimum
value. This is done by simply reversing the output entries for the “Minimum” and “Maximum” fields.
For example, an application requires a 0-10V output signal from the temperature loop for a cooling
output of 0 -100%. On the EZT-570S, 0-100% cooling is represented as a value of 0 to -100%, while
heating is 0-100%. In order to transmit the cooling output, set the “Minimum” to 0 and the “Maximum”
to -100. The output will then produce a signal from 0 volts at an output of 0% (output minimum) to a
signal of 10V at an output of -100% (output maximum).
