12 English (US) 5. Starting up the product WARNING Arc flash and electric shock hazard - Wear appropriate personal protective equipment (PPE) and tools while working on this equipment. CAUTION Toxic material Minor or moderate personal injury - Before starting any work on pumps used to pump liquid which could be constituted as being hazardous to health, a thorough cleaning and venting of pumps, pits, etc. must be carried out according to local regulations. 4. Switch on the power supply. Three-phase pumps only: Check for wrong phase sequence. If the phase sequence is wrong, the impeller will rotate backwards. 5. Check the direction of rotation before starting up the pump. An arrow on the stator housing of most Grundfos pumps indicates the correct direction of rotation. For a Grundfos pump, check that the direction of rotation is clockwise when viewed from above. See fig. 9. Check the Installation and Operating Instructions for the pump to verify the correct direction of rotation. DANGER Electric shock - Startup must be carried out by authorized personnel in accordance with local regulations. DANGER Electric shock - Before starting any work on the product, pumps, pits, etc., make sure that the power supply has been switched off and that it cannot be accidentally switched on. Proceed as follows: 1. Check that the float switches have been connected according to the wiring diagram for the application. 2. Check that the pump inlet is submerged in the liquid to be pumped. 3. Observe the warning below. Set the overload relay to the rated current stamped on the pump motor nameplate. DANGER Electric shock - Set the overload relay to the rated current stamped on the pump motor nameplate. Fig. 9 The correct direction of rotation is clockwise for most Grundfos pumps For Grundfos pumps: Check the direction of rotation when connecting the pump to a new installation. The direction of rotation can be checked in the following way: Let the pump hang from a lifting device, e.g. the hoist used for lowering the pump into the tank. Start and stop the pump while observing the movement (jerk) of the pump. If connected correctly, the pump will rotate clockwise, i.e. it will jerk counter-clockwise. If the direction of rotation is wrong, interchange any two of the phases in the power supply cable. Check that a stop float switch is installed to ensure that the pump does not dry run. If the pump is dry running, increase the height of the stop float switch. Three-phase pumps: Check that the direction of rotation of the pump is correct according to the installation and operating instructions for the pump in question. Select the required operating mode by means of the automatic/manual/off toggle switch. TM

13 6. Liquid level control 6.1 Float switches SLC and DLC control panels are available with float switches for automatic level control. Float switches are available as accessories. Grundfos float switches are of the non-mercury type and are available for standard and explosion-proof pumps. The hermetically sealed polypropylene housing and polyurethane cable make Grundfos float switches resistant to many chemicals, e.g. alcohol, uric acid, sewage, oils, gasoline and fruit acid SLC The SLC can be fitted with up to three float switches: Minimum: Stops the pump. Maximum: Starts the pump. Alarm (optional): Indicates high water level or pump failure DLC The DLC can be fitted with up to four float switches: Minimum: Stops both pumps. Maximum 1: Starts one pump. Maximum 2: Starts the other pump. Alarm (optional): Indicates high water level or pump failure Locating and positioning the float switches Install the float switches in the water collecting tank or pit floating on the pumped liquid. A float switch is an accepted way of controlling liquid levels in tanks, pits, etc. The position of the float switches determines when the SLC or DLC will start and stop the pump(s) Function of the float switches Suspend the float switch, encased in a drop-shaped polypropylene housing, at the desired height by its own threecore cable. When the liquid reaches a certain level, the float switch will tip either up or down, causing the contact to open or close. When the float switch is pointing up, the float switch contact will be closed and the pump will start. When the float switch is pointing down, the float switch contact will be opened and the pump will stop.

26 English (US) 9.7 Control panel operation SLC, float-switch-controlled option The control panel supports two different modes of operation based on selected parameter settings. See section 9.9 Adjustable parameters for information on how to change the mode of operation and other adjustable parameters. Your control panel can perform the float functions listed below. Depending on the application, some functions may be omitted or combined. High Level Alarm Pump On Pump Off Pump Fault* This float switch activates the alarm indication on the screen and the audible alarm when lifted for longer than the high-level alarm delay. Press the Push-to-Silence button on the side of the control panel to silence the audible alarm. The alarm indication on the screen will remain on until the float switch is lowered, and the audible alarm will reactivate in 12 hours if the alarm condition is not corrected. This float switch starts the pump when lifted. The pump will run for the duration of the minimum run time or until the pump-off float switch (if used) is lowered. This float switch stops the pump(s) when lowered if the minimum run time has elapsed. The pump failure is activated when the pump overtemperature sensor, seal failure sensor, or overload protection has tripped. A pump failure will activate the alarm indictor light, the audible alarm, and an alarm message on the user's screen. Press the Push-to-Silence button on the side of the control panel to silence the audible alarm. * To determine a pump seal failure, overtemperature or overload trip, open the dead-front inner door and look for the following relay conditions: Overload relay: When the overload relay trips, the trip indicator is present on the device. The overload relay can be reset by pressing the blue reset button. The overload relay can be switched to manual or automatic resetting. K02: This relay is active when the overtemperature sensor in the pump has tripped. K03: This relay is active when the seal-failure sensor in the pump has tripped. 26
