The control unit is rated for a connection voltage of 220 VAC. It is also available fora 110 VAC connection voltage. When a motor starter is integrated, the operatingconnection voltage is stepped down correspondingly.

Before operating the control unit, check the rated or connected voltage indicatedon the red rating plate inside the cabinet.Make sure that the solenoid valves for operating water and control air are rated for24 VDC.

The electrical feed to the control unit must be protected by a 10 A slow-blow fuseor the rated currents of the motor starters must be adjusted in accordance with thedata in the circuit diagram.External voltagesThe potential-free contacts of the output modules carry external voltage (evenwhen the main switch is off!). They can be identified by the orange coloured wiring.They can be included in circuits with any voltage 250 VAC.For the switching capacity of the contacts: see 3.1A wire cross-section of 1.0 mm2, copper, is adequate for all cables. The arrange-ment of the terminals on terminal strip X1 is shown in the terminal diagram in theappendix.The screwed glands for the electrical cables should be properly tightened andpacked with sealing compound.

Valve actuation is via fuse terminals with LED indicators.When there is a short-circuit in the valve electric circuit, the fuse in the terminal re-sponds which is indicated by the corresponding red LED. This single fuse arrange-ment guarantees the full functionality of the C7-623/A control unit, as the operatingvoltage 24 VDC is still available. The electronic fuse in the power supply module isnot activated.

Attention!When the fuse monitoring responds, the function of the separator is limited (valvedoes not work).Eliminate the cause of trouble immediately!Spare fuses 0.5 A - semi-time lag are supplied with the control cabinet.

When using time-dependent automatic control programs, accurate setting of theseparation time (time between ejection cycles) is only possible if the throughput ca-pacity and solids loading in the feed remain constant. If this is not the case, it maybe necessary to correct the settings during operation.The separating time depends on the preselected operating mode (partial or total ejection mode), the solids loading in the feed, the consistency of the solids, the effective sludge space volume in the bowl, the separator throughput and the desired bowl cleaning effect.The recommended time settings for the different separator models and their specialfunctions are given in the table in chapter 4.7 on page 48.Given constant conditions, the separating time can be determined by calculationor with the aid of the diagram (see overleaf).

Example for calculating the separating time:Given: Solids loading p = 0.05%

Sludge space volume V = 1.5 lSludge space with 75 % utilization V = 1.13 lThroughput capacity Vo = 2 000 l/h

Wanted: Separating time t = ? min

The separating time to be adjusted is calculated as follows:

V 1.13t = 60 100 = 6 000 = 67.8 min = 1.1 h

V p 2 000 0.05
