English • Water and water/glycol mixtures in a maximum ratio up to 1:1. High glycol concentration and low temperature systems may require a reassessment of the hydraulic data to compensate for the increased viscosity (please contact your WILO representatives for more information). Use of additives (corrosion inhibitors, oxygen scavengers etc.) must be in compliance with the manufacturer instructions. • If other fluids or additives are used, please contact WILO for proper authorization.
English Min. pump inlet pressure [psi] at the suction side during operation by WiloStratos model: At these liquid temps TMed 1.25 inch 1.5 and 2 inch 3 inch 14°F...122°F (- 10°C...+50°C) 203°F (+95°C) 230°F (+110°C) 4.4 (psi) 7.3 (psi) 10.2 (psi) 14.5 (psi) 17.4 (psi) 21.8 (psi) 23.2 (psi) 26.1 (psi) 33.4 (psi) The values apply up to 984 ft above sea level, add-on for higher altitudes: 0.15 psi/328 ft increase in height 5.
English The main benefits of electronic control are: • it saves energy while reducing operating costs, • it reduces noise caused by the excess flow, • it does not require pressure bypass valves. This wet rotor pump is designed to have all rotating parts surrounded by the liquid being pumped. The pump is maintenance free and requires no further maintenance after the air bleeding procedure during the initial start-up (no after start-up maintenance).
English 6.2.2 Differential-pressure control systems The control systems which can be selected are: • 'p-v: (Factory default setting) The electronics increase the pump's differential pressure set point in a straight line between ½ Hs and Hs. The differential pressure set point Hs increases or decreases in accordance with the required flow rate (fig. 6).
English • Pump kick: Any pumps switched off via the menu (ON/OFF), a bus communication, the infrared interface, the Ext.Off control input or 0-10V start running for a short time every 24 hours to prevent blockages in the event of long periods of standstill. The mains voltage must not be interrupted for this function. If the mains is intended to be switched off for a long period of time, the pump kick must be assumed by the heating/boiler control system by briefly switching on the mains voltage.
English • In the event of a break in communication: The slave pump runs at the last set value of the master prior to the interruption. • Pump swap: If only one pump is operational (duty/standby, peak- or low-load operation), the pumps are swapped after every 24 hrs’ of actual operating time. Both pumps are running at the time of the pump alteration in order to ensure that operation is not interrupted.
English Symbol Definition Manual control mode deactivates the module pressure variations. The speed of the pump is kept at a constant level. The speed is set internally using the contol button (fig. 9). Pump set to a constant speed (2.600 rpm example shown) - manual control mode. In the manual control mode, the speed or nominal lift of operating mode 'p-c or 'p-v of the pump is set via input 0...10 V of the Stratos IF module Ext.Min. The button then has no set value input function. (fig.
English Menu structure: There are three menu levels. The levels beneath the display of the basic settings are always accessed from 1 level by pressing the control button for different lengths of time.
English • The pump must be installed in an easily accessible position to facilitate inspection or replacement. • The pump should never be located at the lowest point of the piping system, where dirt and sediment collect. Nor should it be located at the highest point of the piping system, where air accumulates. Please ensure at least a minimum of three pipe diameters of straight on the suction side of the pump.
English DANGER! Electrical shock hazard! If the pump is operated by means of a generator, a dangerous voltage is created at the motor terminals after the control module is removed. The motor terminals are designed as VDE-approved bushings, so that there is no danger if simply touched with the finger. However, there would be a danger if a pointed object (nail, screwdriver, wire) were poked into one of the bushings. 7.1.
English 7.2 Electrical connection • • • • DANGER! Electrical shock hazard! Dangers caused by electrical energy must be excluded. Electrical work by a qualified electrician only! National Electrical Codes, local codes and regulations must be strictly followed. All electrical connections must be performed after the electrical supply has been switched off and secured against unauthorized switching.
English 7.2.1 Electrical pump connection (fig. 5) • 230 V~, : Mains voltage, single-phase current 1~230 V AC ±10%, 60 Hz Voltage across terminals “230V~” must be total 230 volt either • 230 volt “hot” lines and neutral line or • two 230 volt “hot” lines. • FC: A built-in collective fault signal is available on the FC (fault contact) terminals as a potential-free closed contact. Permissible contact load: • minimum: 12 V DC, 10 mA, • maximum: 250 V AC, 1 A. Max.
English 8 Commissioning 8.1 Filling and Venting • Proper fill and pressurize the system with liquid. CAUTION! Possible damage of the pump! Never operate the pump dry. The system must be filled before starting the pump. Ensure that all isolation valves are open. • The pump is normally vented automatically after a short operational period. WARNING! Risk of burning! Depending on the operating condition of the pump and/or installation (fluid temperature) the entire pump can become very hot.
