![]() A phase selection switch is included for three-phase control panels. As an option, a phase selection switch can be provided for three-phase control panels.Īnalog Voltmeter (PV): Indication of voltage on one phase and all phases for single-phase and three-phase respectively. Main advantages is that the drives modulate actual motor speed according to demand providing energy cost savings particularly in applications with less than 50% static head, reduce mechanical stress on the motor and shaft, lower starting (in rush) current, reduce water hammer effect and check valve slamming.Įxample: 1PDS304 – One pump, DOL start Standard panel, three-phase 4kW, 2PYP345 – Two pump, YD start, Premium panel, three phase 45kWĪnalog Ammeter (MA): Indication of current on one phase. Control panel specification includes incoming isolator, individual pump fuses/breakers, ATV630 VFD starters, enclosure thermal management fans and thermostat, ‘On’ and ‘Trip’ indicators, Start-Stop push button, emergency push button and Auto-Off-Hand Selector Switch. Altivar process drives have advanced application functions dedicated for water pumping in industrial and commercial applications, embedded services such as energy and pump efficiency monitoring dashboards without additional softwares and integral Modbust/Ethernet protocol connectivity interfaces allowing seamless integration to BMS systems. Standard control panels for Variable Frequency Drive (VFD) starters using premium Schneider Electric Altivar Process Drives. ![]() They also lower starting current and system electrical load reduce water hammer effect and check valve slamming. The advantage of these panels is that they reduce mechanical stress on the motor and shafts for extended motor life. Specification includes Incoming Isolator, individual pump MCB’s, SOFT-STARTER, Line and Bypass Contactors, ‘On’ and ‘Trip’ indicators, Start-Stop push button, Reset push button and Auto-Off-Hand Selector Switch. Specification is as for type 1&2PD with the alternative fitting of a Star-Delta Starter(s) with three Contactors, Overload Relay and Timer. Two pump panels have paired component sets and a 102 Changeover when CCA (Auto Cycle & Auto Trip Changeover) is specified and individual Auto-Off-Hand Selector Switches when independent pump operation is specified. Specification includes Incoming Isolator, individual pump MCB’s, DOL Starter (Contactor & Overload relay), ‘On’ and ‘Trip’ indicators and Auto-Off-Hand Selector Switch. Standard panels for Direct-On-Line (DOL) start. These are suitable for use with single phase borehole motors where control box is provided complete with capacitors. Two pump panels have paired component sets with a 102 Changeover switch. Specification includes Incoming isolator, MCB, ‘ON’ indicator and (motor sizes> 1.1kW), Relay and Auto/Hand selector switch. Manual panel for small single-phase pumps. ![]() Generally panels are fitted with quality Schneider components though other premium brands including Lovato, Siemens and ABB are available on request. Motor Manufacturers usually specify the starting methods and voltage on the motor name plates.Īll panels are available in two quality specifications Standard panels are categorized based on the Starting Methods of the motor. Free standing enclosures can be provided on order.Īll panels are manufactured to exacting standards and are quality products which complement the wide range of pumps available from DAVIS & SHIRTLIFF to provide cost effective, reliable and efficient water installations. As a standard, the enclosures are wall mounted type with hinged lockable door fronts. The degree of ingress protection is IP54 or higher. Enclosures are manufactured of mild steel and finished with a hard baked non-chip dry powder epoxy finish. Comprehensive wiring diagrams are provided with all panels. Panels for multi pump, large motors and specialised control applications can also be supplied, these being individually designed to suit the particular installation.Īll panels utilise quality components and are supplied completely pre-wired with terminals for control accessories (where applicable) as well as incoming and outgoing power connections. In addition various optional accessories are offered so panels can be customised to suit site requirements. Standard panels are available for one and two pump installation in all sizes up to 90kW for both manual and automatic installations operation. The DAYLIFF range of pump control panels have been specially designed to provide effective protection and reliable control of all electric pumps.
