1. General description

SLC and DLC pump control panelsThis document provides information about Grundfos SLC and DLC pump control panels including options, accessories, installation information, and product range.

Grundfos SLC and DLC pump control panels are designed for level control, monitoring and protection of pumps in wastewater, water supply and drainage systems.

SLC and DLC pump control panels are designed for emptying (water removal) applications. For boosting applications, see the Grundfos BoosterpaQ product line.

The SLC and DLC control panel product range comprises models up to 45 A / 15 hp (P2), direct-on-line starting (DOL).

Fig. 1 Grundfos DLC pump control panel

SLC - for one pump (Simplex)Float-switch-controlled option

The SLC, float-switch-controlled option, enables control of one (1) pump, utilizing the following inputs:

– high water-level alarm

– pump on

– pump off.

Transducer-controlled option

The SLC, transducer-controlled option, enables control of one (1) pump, utilizing an analog submersible level transducer with float-switch alarms:

– 4-20 mA (analog) water-level detection for duty and standby pump control

– high water-level alarm float switch

– low water-level alarm float switch.

DLC - for two pumps (Duplex)Float-switch-controlled option

The DLC, float-switch-controlled option, enables control of two (2) pumps, utilizing the following inputs:

– high water-level alarm

– duty pump on

– standby pump on

– pump(s) off.

Transducer-controlled option

The DLC, transducer-controlled option, enables control of two (2) pumps, utilizing an analog submersible level transducer with float-switch alarms:

– 4-20 mA (analog) water level detection for duty and standby pump control

– high water-level alarm float switch

– low water-level alarm float switch.TM

– run time

– operating cycles (counter)

– seal-failure alarm

– high-temperature alarm.

• one (1) motor contactor per pump

• one (1) motor circuit protector per pump

• a 95 db audio alarm

• an Automatic-Manual-Off toggle switch for each pump

• an alarm beacon light

• a pump run light for each pump

• a specific pump alarm display text for each pump

• a push-to-silence alarm button

• auxiliary contacts (NO/NC) for alarm.

Additional options• Battery backup with charger (for alarm only)

4. Accessories

Float switchesSLC and DLC control panels are available with float switches for automatic level control. 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.

SLCSLC 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.

DLCDLC 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 switchesThe float switches must be installed 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 SLC or DLC will start and stop the pump(s).

Function of the float switchesThe float switch, encased in a drop-shaped polypropylene housing is suspended at the desired height by its own three-core 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.

5. Functions

The SLC and DLC control panels include an easy-to-use programmable logic unit that incorporates many timing and logic functions.

The pump control panel features alarm and data screens to assist with monitoring and troubleshooting. The up- and down-arrow buttons allow you to navigate between the screens.

See the following table and screen navigation section for more details.

The alarm screen will only be displayed when alarms are active. The alarm screen shows the date and time when the alarm started.

Control panel operation

SLC, float-switch-controlled optionThe control panel supports two different modes of operation based on selected parameter settings. See Adjustable parameters on page 22 for information on how to change the mode of operation and other adjustable parameters.

Your control panel can perform the functions listed below. Depending on the application, some functions may be omitted or combined.

* 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.

High Level Alarm

• 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.

Pump On• 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.

Pump Off • This float switch stops the pump(s) when lowered if the minimum run time has elapsed.

Pump Fault*

• 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.

Pump alternationDLC pump control panels support four different modes of operation relating to pump alternation which are based on selected parameter settings. Additionally, the panel can be set to alternate pumps in the event of a failure.

See Adjustable parameters on page 22 for information on how to adjust these parameters.

Alternating (default)• Parameters "Pmp1Lead" and "Pmp2Lead" are set to "Off".• The (duty) and lag (standby) pumps will alternate for each cycle.• This mode provides equal wear on both pumps and is recommended for most applications.

Pump 1 Lead

• Parameter "Pmp1Lead" is set to "On" and parameter "Pmp2Lead" is set to "Off".• The lead (duty) pump function is locked to pump 1 and the lag (standby) pump function is locked to pump 2.• No alternation will occur.• Pump 1 will be the primary pump for the system.• Pump 2 will only be used during high-flow conditions.

Pump 2 Lead

• Parameter "Pmp1Lead" is set to "Off" and parameter "Pmp2Lead" is set to "On".• The lead (duty) pump function is locked to pump 2 and the lag (standby) pump function is locked to pump 1.• No alternation will occur.• Pump 2 will be the primary pump for the system.• Pump 1 will only be used during high flow conditions.

Both Pumps • Parameters "Pmp1Lead" and "Pmp2Lead" are set to "On". Both pumps will run in every cycle.

Adjustable parametersSLC and DLC pump control panels include an easy-to-use programmable logic unit that incorporates many timing and logic functions.

The unit has been programmed from factory for the control functions required. The unit includes adjustable operational parameters and viewable monitoring information. Some operational parameters may need changing for your particular application.

SLC and DLC pump control panels use block names to identify the various parameters. Please refer to the screen of the logic controller face inside the enclosure.

Block names, SLC float-switch-controlled optionThe following block names are used for SLC, float-switch-controlled option.

All adjustable parameters DO NOT use the same type of blocks. Check the block types below to determine which steps apply to your application.
