11 Configurable relays
Depending on TCU model, can add up to 2 configurable relays for user process automation. Making the TCU
unit in a process control system.
These switched relays with potential free contacts (support up to 6A), listed as r2 and r3 in the St-4 menu,
can be configured to work with the control signals incorporating the TCU unit (which are activated by
exceeding the value programmed), are:
Pump pressure.
Return pressure.
Outlet process temperature.
Inlet process temperature.
Flow lit/min in return process.
General alarm.
Examples:
The user needs to know when the mold temperature has reached the value he wants to start the process.
Through external thermocouple located in the mold provided by the user to the TCU unit, will control the
temperature using the r3 relay.
When the temperature exceeds the set value, the relay r3 provide the user a signal it allow to start the
application.
If the mold have no thermocouple could be done as follows:
We will control the temperature of the return process by
the thermocouple at the temperature control unit with relay r3.
Check externally (contact thermocouple, laser gun) when the mold is at optimum operating temperature, and
display on the screen which is the return temperature at that time. In this way we could set the value in the
relay r3, which will provide the user for future occasions, the signal to start its application in this mold.
