Siemens LU01 P100 Preset Applications, Option Relay # Point # Standard Alarm as % of Span, P007

Parameters

Setpoints are set up in P112 and P113. Each relay is triggered by one or more setpoints. The setpoints can be based on absolute level (P112, P113) or rate of change (P702, P703). Each control function specifies which setpoints are required.

P100 Preset Applications

This parameter presets relays to operate as Standard Alarms. The Relay Allocation (relay/point number association) and Standard Alarm (P101 to P104) parameters are also preset.

Relay status during a measurement difficulty is dependent upon Failsafe programming. See Failsafe Parameters (P070 to P072) and Relay Failsafe (P129). As preset, relay status is held at last known material levels until a valid measurement is made.

Independently altered Standard Alarms (P101 to P104), Relay Allocation (P110), Relay Function (P111) and Relay ON/OFF Setpoints (P112/P113) are automatically reset when a Relay Set Up value is altered. .
