FRONT PANEL OPERATION
The PXZ controller programming menu consists of two blocks—
PRIMARY (SETPOINT) MENU and SECONDARY (SYSTEM) MENU. At
power up, the controller will be in the operational mode– process
variable (PV), in the case of PXZ4, and both process variable and set-
point variable (SV), in the case of PXZ-5, 7, 9 will be displayed. PV is
the variable that is being controlled, and it is not programmable.
When setting the parameters, turn off the power to the load (operat-
ing equipment) to ensure safety. Since it takes 30 minutes for the unit
to stabilize in terms of temperature, all measurements should be car-
ried out at least 30 minutes after the power is turned on. Option-relat-
ed features are displayed only when the options are provided.
Viewing and Setting Parameters
• After setting the data, press ENT key for registration.
• If the data setting is left as it is for 30 secs, the display is automati-
cally returned to the operational mode.
