In general:

When configuring the 4623, you will be guided through all parameters and you can choose the settings which fit the application. For each menu there is a scrolling help text which is automatically shown in line 2 on the display.

Configuration is carried out by use of the 3 function keys:

Λ will increase the numerical value or choose the next parameter

νwill decrease the numerical value or choose the previous parameter

OK will save the chosen value and proceed to the next menu

When configuration is completed, the display will return to the default state 1.0.

Pressing and holding oK will return to the previous menu or return to the default state (1.0) with saving the changed values or parameters.

If no key is activated for 1 minute, the display will return to the default state (1.0) with saving the changed values or parameters.

Further explanations:

Fast setpoint adjustment and relay test: These menus allow you to make a quick setpoint change and relay test when the FastSet menu is activated. This function can only be activated when the relays are set for setpoint function and are controlled by a setpoint.

Pressing OK will save the setpoint change.

Pressing and holding oK will return the unit to the default state with saving the setpoint change.
