LEARNING OBJECTIVE
● The content delivers complete technical knowledge of control, monitoring, and distribution systems described in Schakelschemaboek 2008.
GENERAL INTRODUCTION
● Schakelschemaboek 2008 compiles structured electrical diagrams for automation and energy distribution.
● The document includes detailed functional definitions of each listed component.
● Eaton is the corporate entity managing the Moeller brand. ⚙️
CONTROL AND AUTOMATION DEVICES
● The easy500 programmable relay offers digital and analog input management with timing and counting functions.
● The easy700 shares the same processor with expanded input and output capacity.
● The easy800 extends capacity with PID control, arithmetic blocks, and scaling. 🖥️
● MFD-Titan provides IP65-rated display and operator interface with alarm and message functions.
● eControl EC4P-200 is a PLC with Ethernet communication and IEC 61131-3 programming.
● easySafety integrates emergency stop, optical curtain, and two-hand control functions.
MONITORING RELAYS
● EMR4-I monitors AC or DC current with selectable delay to filter peaks.
● EMR4-W monitors phase sequence and voltage levels to prevent equipment damage.
● EMR4-F ensures correct rotation direction of three-phase motors. 🔌
● EMR4-A detects phase loss and asymmetry to protect motors from overload.
● EMR4-N uses conductive level sensing for liquid control and pump protection.
● EMR4-R performs insulation monitoring with optional fault memory and test button.
TIME RELAYS
● Function 11 applies on-delay switching for controlled start sequences.
● Function 12 applies off-delay switching for controlled stop sequences.
● Function 21 outputs a timed pulse on activation. ⏱️
● Functions 42 and 43 perform flashing cycles with impulse or pause start.
● Function 51 enables star-delta motor starting.
● Functions 81 and 82 produce fixed or programmable output pulses.
INPUT AND OUTPUT CONNECTIONS
● AC devices accept contact, pushbutton, or limit switch signals.
● DC devices require three- or four-wire sensors for reliable operation.
● Analog inputs accept 0–10 V or 4–20 mA with shielding and grounding rules. 🛠️
● Potentiometers of 1 kΩ are typical for setpoint input at 24 V DC.
● 500 Ω resistors adapt current signals to voltage measurement range.
POWER DISTRIBUTION SYSTEMS
● xEnergy is a modular switchboard system rated up to 4000 A.
● CS enclosures are metallic with IP55 and IK10 protection.
● CI enclosures are plastic with IP65 protection for harsh environments. 🗄️
● SASY60i is a modular busbar system compliant with IEC and UL standards.
● Terminal blocks K support copper conductors or busbars up to 3×240 mm².
SERVICE AND SUPPORT FUNCTIONS
● Telephone assistance is available for technical troubleshooting.
● Onsite service includes maintenance, inspection, and thermography.
● Repairs and replacements reduce downtime in critical installations. 🔍
● Online service provides diagnostic tools, software downloads, and FAQs.
