Controls Pump Controls Function The pump controls consist of the level sensor and the control cabinet with the associated accessories such as auxiliary relays, contactors, switches, control lamps etc . The control cabinets are tested and the wiring is effected via a terminal strip, ready for connection . 146 Design Pump controls are divided into two groups: systems with fixed digital switchpoints (NRSP 1-1 .) where the switchpoints are determined by the length of the electrode tips, and systems with variable switchpoints that can be adjusted to the varying process conditions (NRSP 2-1) . Standard equipment Type NRSP 1-11 NRSP 1-12 NRSP 2-11 NRSP 2-22 Run-dry alarm – – Run-dry and high-level alarms – – Time-dependent pump changeover – – Connection point for stand-by-pump – – – Collective malfunction message (visual) – – Collective malfunction message (visual & acoustic) – – Volt-free contacts Remote level indication – – – Programmable logic controller (PLC) Function The PLC are customised system solutions for individual control functions and used in pump controls, steam regenerators, desuperheating installations, injection coolers, steam driers etc . The control systems are based on the S7-300 module and feature a malfunction log and an Operator Panel that allows the user to visualise and parameterise controlled systems . A connection to higher ranking bus-based control systems or volt-free digital signals is available as optional extra . Design The PLC is based on the Simatic S7-300 and consists of a CPU (optional extra: Profibus DP interface) and digital and analog input and output components . To monitor and operate the equipment the Operator Panel is designed as line display or with full graphical display capability for installation in control cabinets . The conventional controllers can therefore be dispensed with and the variable switchpoints, e .g . for the NRSP 2-1, can be adjusted . The malfunction log lists and stores all malfunction messages, with time and date being added .
