Siemens 200 instruction manual Backup Level Override Parameters

Backup Level Override

Backup level override provides the option of overriding the ultrasonic input with another contacting point level device, for example, the Pointek CLS200. The ultrasonic reading is fixed at the programmed switch level until the discrete input is released and the ultrasonic device makes its decisions based on the override value.

Backup Level Override Parameters

P064: Reading Override Enable

Sets the discrete input as the source of a level reading override.

P065: Reading Override Value

Substitutes value for current reading when the discrete input (P064) is enabled. Value is added in current units and is valid only for the following:

•level

•space

•distance

•difference

•average modes of operation

•head level in OCM mode

Example:

A high level backup switch is connected to Digital Input Two in the same application as Transducer One at level value 4.3 m.

Settings

Parameter	Index	Value
P064	1	2
P064	2	0
P065	1	4.3
P065	2	–

When the level rises to 4.3 m and the switch is activated, the reading is forced to 4.3 m where it stays until the switch is de-activated.

P066: Override Time Delay

Sets the time (in seconds) used to calm the override condition input.
