Communications Example
In this example, the E5ZE is operated with Heater Burnout and SSR Failure
Detection Current Value Read (RW) under the following conditions.
Unit no.: 1
Control Point: 3
Heater Burnout Detection Current Value: 25.0 A
Command
Response
5-5
Heater Current Value and SSR Leakage Current Value
Read: RZ
Function
This command is used so that the E5ZE can read the current value of the
heater or the leakage current value of the SSR connected to a control point
via the Current Transformer.
1.
Heater Current Value: The current value of the heater measured at the
control point with its control output turned ON.
2.
SSR Leakage Current Value: The leakage current value of the SSR mea-
sured at the control point with its control output turned OFF.
Command
Response
The current data of the response block for Heater Current Value and SSR
Leakage Current Value Read (RZ) will be 0000 in the following cases.
