Construction and features of the Wilo-Comfort controller CC

Wilo-Comfort controller CCHardwareSystem control panel, NEMA 12 enclosure, with main disconnect and built in frequency converter.

Control panel featuresThe components of the control panel are dependent on the horse-power of the pumps (direct starting or star/ delta start-up). It is made up of several components:

Main disconnect: Switches the control panel and system on/off.

Touch screen: Graphics-ready touch screen built into the control panel cabinet door for adjustment and status readout. Displays sys-tem operating data and the current operating status of each pump, controller and the frequency converter by means of the combination of symbols, diagrams and a multi-language plain text display. Up to 15 different languages are stored and/or programmable. Operating status is also displayed by means of alternating backlighting colors on the touch screen. The touch-sensitive surface is used to select menus and menu items and to enter parameters.

Programmable logic controller (PLC): 24 volt PLC module - configu-rations are system dependent and custom programmed during facto-ry set-up. Included is a central unit (CPU) analogue 24 volt module. Additional digital modules and a COM interface are included.

Fuse protection of controller and frequency converter: Up to 5 Hp with motor overload, 7 ½ Hp and above via contactor/contactor combinations including thermal actuator and time relay for star-delta starting.

Hand off Automatic (HOA): Hand "H" (emergency/test operation on the power supply and individual pump test), off "O" (pump switched off - no actuation possible via PLC) and "Auto" (pump enabled for au-tomatic operation via PLC).

Frequency converter: Panel mounted Variable Frequency Drive for the speed control of the base load pump

External On/Off: Terminals for external On-/Off switching by manual remote actuation.

Collective run/fault signals: Potential-free contacts per wiring dia-gram, maximum contact load 250 V~/2 A

Individual run/fault signal and low water level signal: Additional po-tential-free contacts for remote monitoring of specific individual faults or low water or system pressure problems. Maximum contact load 250 V~/2 A

External pressure input signal option: Pressure transducer inputs between 0-10 V. 10 V corresponds to the pressure sensor limit value, e.g. 10 V = 235 PSI with a 235 PSI transducer.

External frequency input option: The frequency signal can be input-ted via corresponding terminals using a 0-10 V signal for external measurement /display options. 0-10 V corresponds to 0-60 Hz.

Fault display and acknowledgement: In the event of a fault, the color of the backlighting will switch from its normal GREEN to RED. The collective fault signal is activated and displayed on the screen with fault code number and alarm text. A message is sent to the user defined recipient(s) in systems equipped with remote diagnostics. An acknowledgement can be performed using the RESET switch on the screen or by a remote signal when equipped. During reset, the back-lighting of the display then switches from RED to ORANGE. The back-lighting of the display does not switch back to GREEN until the fault has been remedied.

Time display: All failure stopped times are recorded on the screen in real time. This also applies to power failures, (the real time clock con-tinues to be operated with a backup battery). Charge status of the real time clock backup battery is monitored by the system and dis-played on the screen.

Software• Fully automatic control for 2 to 4 pumps with VFD with 4 - 20 mA

pressure transducers with wire-break detection.• Menu navigation in plain text in up to 15 languages and/or additional

symbol display.• User defined with or without standby pump.• Test run can be switched on/off, user programmable.• Pump usage balanced via operating run hours.• Optional pump cycling via user regardless of operating hours• Optional rotating base load pump with each system start-up • Optional fixed base load pump. All peak-load pumps are alternated

on a service life optimization basis• Accumulated individual pump run time recorded.• Accumulated system run time recorded.• Automatic changeover in the event of a fault from system pump to

standby pump.• Low-water cut-out via signals from a suction-side pressure switch,

transducer or float switch after an adjustable low limit time. Also possible by means of immersion probes and level relays (optionally available).

• Monitoring of maximum and minimum system pressure with adjusta-ble time/pressure graph

• 3 level operator programming security levels• Fault recording.• Weekly clock timer, e.g. for 2nd pressure level.• 2 individual system program can be selected.• Factory-preset programming for easy commissioning/start-up.• Deactivation of the base-load pump by means of zero-flow test (ad-

justable increasing of the set point every 60 s for 5 s., monitoring pressure and speed), if the actual value does not fall, then base load pump shuts off after adjustable run time.

Accessories for the CC controllerOptionally available modules

Battery-backed power supply unit: The power supply of the PLC re-mains on, in the event of power failure

PTC evaluation relay: Over-temperature monitoring for pumps with PTC resistors.

Remote set point adjustment or manual control mode: The set point can be modified by means of an external analogue signal (0-10 V, 4-20 mA) or the control device runs in manual control mode by means of external analogue signals.

Individual run and fault signal: Potential-free contacts for remote signaling of the pump status.

Electrical connectionSee chapter “Electrical connection” for the respective system.

Function descriptionThe Wilo-Comfort pressure boosting system is controlled and moni-tored by means of the CC Comfort Controller in conjunction with var-ious pressure and level sensors. The Comfort control system, control-

led by a programmable logic controller (PLC), is used to control and regulate pressure boosting systems with up to 4 individual pumps, with the system pressure being monitored through corresponding pressure transducers and kept within the programmed pressure rang-es by the PLC. The PLC controls the frequency converter, which in turn controls the speed of the base-load pump. The frequency con-verter affects only the base-load pump. Speed changes in the base load pump effects the system flow and thus the power output of the pressure boosting system. Constant speed peak-load pumps are switched on and off automatically according to changes in the load as necessary once the variable speed base load pump reaches maximum speed (slowing down as the peak load comes on line), while the base-load pump handles fine-tuning to the system design pressure set point. The control systems are custom designed depending on the number of pumps and the control requirements. Splitting the total unit capacity between a number of small pumps ensures constant adjustment of the system flow while maintaining constant system pressure.

System function with frequency converterThe system pressure will remain constant with varying flow demands. During pump switchover (pump reaching maximum frequency and speed) the pressure will fall to the switch-on level pOn for cut-in of the next (peak-load) pump. The same applies to cut-out of peak-load pumps: the pressure will only rise to the required switch-off lev-el pOff on reaching the 100% speed limit. Any excessive pressure surges due to switching the peak-load pumps on or off will be mainly compensated for by the frequency converter lowering or raising the speed of the base-load pump, thus ensuring a soft transition in line with load variations commonly encountered in varying flow demand applications.The pressure boosting system switches on when the system pressure drops to the switch-on pressure level pOn, with a “soft start” base-load pump controlled by the frequency convert-er.The pressure boosting system is switched off via the controller when the system flow demand reaches zero flow. Water hammer caused by hard cycling various pumps is eliminated.
