Eltako BZR12DDX-UC operating hours pulse counter 1We potential-free 22001430

Digitally adjustable operating hours pulse counter with alarm relay and reset. Stand-by loss only 0.05 to 0.5 watts. With the Eltako Duplex technology (DX), the normally potential-free contacts can still switch at zero crossing when switching 230V AC 50Hz, thus drastically reducing wear. To do this, simply connect the N conductor to terminal (N) and L to 1 (L). This results in an additional stand-by loss of only 0.1 watts. As soon as the supply voltage UC is applied to B1/A2, the BZR12DDX can be set: The function is selected using the protruding MODE and SET buttons: Briefly pressing MODE causes the last set function (factory setting BST = operating hours counter) to flash in field 1 and using SET you can now switch to IMP = pulse counter up to 9999 pulses and I10 = pulse counter x 10 up to 99990 pulses. Confirm the selected function with MODE. BST function = operating hours counter: Field 3 shows the accumulated operating hours T1 up to 8760 hours = 1 year. Up to 999.9 hours with one decimal place. Field 2 shows up to 99 accumulated operating years T2, if applicable. MODE can be used to activate the alarm time AZT, at which time the relay contact switches from 1-2 to 1-3. AZT flashes and SET increases by 1 hour in field 3. If you press and hold, the time changes quickly. Release and press and hold again to change the direction. Confirm the selected time with MODE. The + sign in field 1 shows a set alarm time. AA flashes and SET activates (display AA+) or deactivates (display AA) the automatic alarm shutdown. As long as the control voltage (= supply voltage) is applied to A1, the operating hours are counted in field 3 and display II in field 1 slowly moves to the right. The remaining alarm time RZT in hours can be displayed by briefly pressing SET in field 3. Pressing SET again switches back to the operating display. During a power failure, the contact switches from 1-2 to 1-3 and can therefore be used for an alarm message if necessary. When the alarm time AZT is reached, the contact switches from 1-2 to 1-3, SET flashes in field 1 and the time display of the alarm duration from 0.1 minutes (m) to 99 hours (h) begins in field 2. The contact position 1-3 is indicated with an arrow on the left in field 1. Acknowledging the alarm: a) If automatic alarm shutdown is activated (AA+), contact 1-3 only closes for 1 second and the alarm time starts again. b) When the control voltage +B1 is applied to AR, the contact switches back; when the control voltage from AR is removed, the alarm time starts again. c) By pressing the SET button for 3 seconds the contact switches back, the alarm time starts again and the operating hours counter in field 3 continues to run as in a) and b).Reset the operating hours counter before an alarm message by applying the control voltage +B1 to AR for 3 seconds or pressing the MODE and SET keys simultaneously for 3 seconds, confirm the RES display in field 1 with SET. The counter is reset to 0, but the alarm time is not changed. Switch on the key lock by briefly pressing MODE and SET at the same time. The flashing LCK display, confirmed with SET, locks the keys and indicates this with an arrow in field 1 in the direction of the printed lock symbol. Switch off the key lock by pressing MODE and SET at the same time for 2 seconds. The flashing UNL display, confirmed with SET, unlocks again. Function IMP = pulse counter and function I10 = pulse counter x 10: Field 3 shows the accumulated pulses T1 to 9999 (99990) pulses. MODE can be used to activate the alarm pulse number AIZ, at which the relay contact switches from 1-2 to 1-3. AIZ flashes and SET increases by 1 pulse in field 3. If you press and hold the button for a longer time, the number of pulses changes quickly. Release and press again for a longer time to change the direction. Confirm the selected number of pulses
