The term "electrician" is defined in VDE 0105. Electronic devices are protected against external interference to a great extent in accordance with the most up-to-date knowledge. Countermeasures can be taken in the event of a fault — e.g. voltage peaks — by fitting standard components (varistors, suppressor diodes, etc.). Be particularly careful when the time switch is used to control [TI м loss amen, dere | Connection diagram: \ N 2. General The time switch can be used as a daily or weekly time switch. 3. Putting into operation ~ entering the current time 3.1 Reset button "Res." a) before each restart b] to erase all stored information and the current time on the display and in the memory.

Programming ~ entering switching times 4.1 IF an entry is not complete a) and the programming sequence is interrupted, the elements which have not been selected yet start blinking. o The time switch returns to the current operating mode b) and the "Prog." key is pressed and held down, the partial entry will be erased after approx. 3 seconds. The display indicates a free memory location. c) and the "Prog," key is pressed briefly, the partial entry will be erased after approx. 15 seconds. The time switch returns to the current operating mode ( |-,, 4.2 Selecting a free memory location Press the "Prog." key, the 1st memory location is displayed. Keep the "Prog." key pressed if switching times have already been entered in this location. The programmed switching times are displayed in succession. The | st free memory location is then displayed. Pressing the "Prog." key again calls the number of free memory locations to the display, e.g. Fr 14. Fr. = UL! indicates that all 20 memory locations are occupied. Note: You may now enter the switching data in any order you wish. You can use your own usual "method of writing" to program the time switch, | possible weekday combinations with the "Day" key 12 3 4 5 6 7 © Mo, Tu, We, Th, Fr, Sa, Su 123456 - 2 Mo,Tu,We,Th,Fr, Sa, — 123 4 5 - - © Mo,lu, We,ïh Fr, - - we mn — L£ —- — — = $a, Su or each individual da of the week, e.g. 1 2Mo If the h+ or m+ key is held down for longer than 2 seconds, the system enters “fast forward" mode. 4.3 Example — switching time: Keys: Display: Mo, Tu, We, Th, Fr Day 29 Че 6.30 h h+, m+ м. Г! Оп SA сеты De Symbols indicating switching status are: @®=ON © =OFF. When programming one press of one “AW key selects © (ON), a second press selects © (OFF). Pressing the "Prog." key saves the programmed data and selects the next free memory location. | The "C3" can also be used to save the programmed data and returns the time switch to the current operating mode at the same time. The same procedure is used to program "Off" commands, A complete entry is transferred to the memory automatically after approx. 90 seconds. 5. Read - Edit - Delete 5.1 Read The "Prog." key can be used fo read through the switching times step by step. Each display represents the content of one memory location. 5.2 Edit Each stored switching command called to the display witch the "Prog." key can be altered or corrected as you wish. The newly entered data simply overwrites the previous entry. Save the edited switching command by pressing the "Prog." key. 5.3 Delete If one or several switching times are to be deleted, use the h+ and/or m+ keys to set the time to —. Then keep the "Prog." key pressed for approx. 3 seconds to erase the memory location, refer to 4.1 b). Pressing the "Res." key erases the entire content of the memory, including the current time. 6. Manual switch functions The "A" key affects the switching output in the following way: possible starting position o Advance OFF | or 2 > ® | Advance ON [0] | < гтапеп! o pe OFF Y permanently ON < a | LA A manvally altered switching command IN or @W is cancelled by the next automatic switchingt time. You can only return to automatic mode from the (9) or [O] function by pressing the "Ñ" key, 7.
