Before installation or commissioning begins, this manual must be thoroughly read and understood by the technical staff involved. If any uncertainty arises, the manufacturer or dealer should be contacted. P3 devices are power electric parts used for regulating energy flow. Protection rating IP00. Standards and guidelines The device and its associated components can only be installed and switched on where the local regulations and technical standards have been strictly adhered to: EU Guidelines 89/392/EWG, 84/528/EWG, 86/663/EWG, 72/23/EWG EN60204, EN50178, EN60439-1, EN60146, EN61800-3 IEC/UL IEC364, IEC 664, UL508C, UL840 VDE Regulations VDE100, VDE110, VDE160 TÜV Regulations Trade body guidelines VGB4 The user must ensure that in the event of: - device failure - incorrect operation - loss of regulation or control the axis will be safely de-activated. It must also be ensured that the machine or equipment are fitted with device independent monitoring and safety features. Setting adjustments - should only be carried out by suitably trained personnel - should only be carried out in accordance with health and safety guidelines Assembly - should only be carried out when all voltages have been removed. QS Test results are archived with the device serial number by the manufacturer. CE The device adheres to the following: Guideline EU 89/336/EWG. EMC standards EN61000-2 and EN61000-4. ATTENTION - High voltage AC 230V~, DC 320V= Classic C1 230/180 - 4 (f) 4 Thyristor Drive - for inductive and ohmic consumer loads’ Applications - speed control of dc motors - 1-quadrant operation, driving - power: up to 720W - tacho control - armature voltage control with IxR compensation - torque control - cascade control speed/current - rectangular current/speed characteristic curve - switch on and switch off logic - mains connection can directly be switched Compact single-board device - European format - pluggable terminal connection (-W) - C1: galvanic connection - C1-4f: galvanic isolation of the control and the power section - fully insulated power semi-conductor - field rectifier Note for C1 devices: Direct mains connection - zero connection >> on thyristor negative electrode potential - all control connections >> on mains potential - switches and poti >> isolation voltage > 1500V Connection via an isolating transformer - zero connection >> with potential isolation - control connections >> to be earthed and shielded Note for C1-4f devices: Tacho control - device >> with potential isolation Armature voltage control - control unit >> with a high impedance mains connection - zero connection (terminal no. 5) must not be earthed Build - switch cabinet mounting according to the VDE, DIN and EU regulations - standard control electronics REG - intrinsically safe power section with current control loop - optional units Galvanic isolation between - the power section and the housing - the power section and the control electronics The distance of air gaps and leakage paths adhere to the VDE standards (>8mm). Components - fully insulated thyristor modules, comfortably over-dimensioned - only components customary in trade and industrially standardised are used - high-quality bases for the IC with external connections - LED displays - DIP switches for the P-I adjustment of the current control loop - precision potentiometers for fine adjustments - plug-in jumpers for the system set-up
