8 BETA Measuring 7KT5 8 time and pulse counters Overview Time and pulse counters are used for the reliable monitoring of production and service times, which enables the exact planning and monitoring of production sequences, maintenance cycles and warranty times. As well as the proven electromechanical time and pulse counters for mounting in distribution boards, we also supply digital time and pulse counters. The fields of application for both counter types are very diverse, such as the recording of operating hours of machines, systems or building management systems, as well as pulse counting for general volume flow counting, registration of starting frequencies, starting cycles or production quantities in systems and machines. Technical specifications Benefits Time and pulse counters help to plan maintenance intervals and ensure high plant availability Versions without zero position and with electric or manual zero position for all applications Flexible application of the digital counters for power supplies of to 150 V DC and 24 to 240 V AC in a single device. 7KT KT KT KT KT KT5 807 Standards DIN VDE ; EN ; UL 863 Approved acc. to UL 863, UL File No. E300537, CSA C22.2 No. 6 and 55 Rated control supply voltage U c VAC VDC Operating range At 50/60 Hz U c Rated frequency Hz Rated power dissipation P v VA <1 <2 Method of operation Counting of Hours Display Drum-type register h Terminals ± screw (Phillips) 1 Conductor cross-sections Rigid mm Flexible, with end sleeve, min. mm Permissible ambient temperature C Degree of protection Acc. to EN IP20, with connected conductors Safety class Acc. to EN 61140/VDE II Permissible humidity % <80 7KT KT5 8 7KT KT KT KT KT5 833 Standards DIN VDE ; EN ; UL 863 Approved acc. to UL 863, UL File No. E300537, CSA C22.2 No. 6 and 55 Rated control supply voltage U c VAC VDC Operating range At 50/60 Hz U c Rated frequency Hz -- 50/60 Rated power dissipation P v VA <1 <2 <1 Method of operation Counting of Pulses Hours Pulses Display Drum-type register LCD h Counting frequency Hz Pulse duration ms Resetting Electrical -- Yes Mechanical -- Yes Terminals ± screw (Phillips) 1 Conductor cross-sections Rigid mm Flexible, with end sleeve, min. mm Permissible ambient temperature C Degree of protection Acc. to EN IP20, with connected conductors Safety class Acc. to EN 61140/VDE II Permissible humidity % <80 /8 Siemens ET B1 10/2008

The pulse counter sums up the number of pulses, e.g. the making operations of devices. A power supply is required at terminals 1 and 3 of the electronic counters so that the device can constantly display the measured values. Once terminal 3 is supplied with voltage (for DC "+"), the counting procedure starts. If terminal 4 is supplied short-time with voltage (for DC "+"), the counter is reset. In the case of electronic counters, the counting result is saved indefinitely in the event of a power failure (EEPROM). On recovery of the power, the counting is continued from the saved value. As well as a modern design, the electronic counter has a 7-digit LCD, which can be reset electrically or manually. * You can order this quantity or a multiple thereof. Siemens ET B1 10/2008 /9

10 BETA Measuring 7KT5 5, 7KT5 6 time counters for front-panel mounting Overview Time and pulse counters for control cabinets, control and mechanical engineering are used, e.g. in boilers, machine tools or compressors. The pulse counters count the starting frequencies. This supports planning for preventative maintenance. In-time and regular maintenance is the best protection against unexpected shutdowns. Time counters count the time in hours with an accuracy of two decimal places (hundredths of an hour).
