100s Electromechanical Time Relays Electromechanical Time Relays DZ 52-S L, DZN 52-S L, DZ 53-S L, DZ 52 L for single voltage Function: ON-delay (AV), DZN 52-S L protected against power failure 1 setting range, divided into 6 or 5 time ranges Contact equipment: DZ 52-S L = 1 timed and 1 instantaneous changeover DZN 52-S L = 1 timed and 1 instantaneous changeover DZ 53-S L = 2 timed changeover and 1 instantaneous NO DZ 52 L = 2 timed changeover DZ 52-S L, ... 72 x 72 General AV (see page D 3/5). The electromechanical time relays are equipped with synchronous motors 5 and solenoid clutches. 4 6 The setting of the time ranges is done on the timer's front by means of a 15 selector switch. Infinitely variable time setting within a range is carried out 7 3 with the aid of a transparent rotary knob. 20 10 The time-remaining indicator moves during operation from the set time in the direction of zero. 1s 2 8 25 5 Function 30 0 1 9 Upon energization of motor and solenoid, the instantaneous contact is actuated and the time delay starts. When the preset time has elapsed, the 0 delay contact is actuated and the motor switched off. 10 Upon de-energization, the clutch, timing mechanism and all contacts go SCHLEICHER into their off-position. If a voltage interruption occurs during the timing cycle, the clutch, the instantaneous contact and timing mechanism go into their off-position. The time relay protected against power failure DZN 52-S L has the same function as described above, but upon energization, the clutch is locked FD 0008 Function Diagram by a blocking pawl, so that even in no-volt condition, the elapsed time is preserved. DZ 52-S L The timing cycle can be interrupted as often as desired. The instantaneous ON-delay (AV) contact remains in the operative position even during the voltage A1/A2 Supply voltage interruption. When the preset time has elapsed, the blocking pawl is 3 B1 /B2 Control signal 3 released, the timed contacts are actuated, and the motor is switched off. 21/24 Instantaneous contact Actuation by impulse: The time relay protected against voltage interruption 21/22 can be actuated by an impulse applied to the clutch, since the locking 15/18 Delayed contact action of the pawl is immediate (separate motor and coil connections). 15/16 The timing cycle starts when the motor is energized. Upon impulse t = Operating time A t t t t t t actuation, the instantaneous contact goes into its operative position until A a A 1 2 3 t = Break time must be > than release time of timing contact a n the timing cycle ends. Upon timing-out it goes back into its off-position. Operating time = ∑ t x 1 The timed contact only opens for about 10 ms. The timed changeover FD 0033 DZN 52-S L contact cannot be switched into its closed position. ON-delay (AV) Resetting: These devices can be mechanically reset to “0”. A1/A2 Supply voltage Resetting DZA 52-S L: These devices can be electrically and mechanically B1 /B2 Control signal reset to “0” only if the mechanical resetting lever has not been locked. If 21/24 Instantaneous contact resetting is necessary after an interruption of the timing sequence, the time 21/22 selector switch must turned to “0”. 15/18 Delayed contact 15/16 t = Operating time A Notes t t t t t A A s ö ö t = Break time must be > than release time of timing contact a t t t t a a a s t 3 t = Closing time must be > than minimum excitation time s u The relay has a frequency switch on the underside of the cover t t t t t = Opening time refers only to the NC contact, 1 3 A 2 ö that can be set to 50 or 60 Hz, depending on the connected external the NO contact is not switched t t 2 1 supply. The factory presetting is 50 Hz. n Operating time = ∑ t u With the exception of the type DZ 53-S L the relays have separate x DZ 53-S L 1 FD 0040 motor and solonoid connections which make the following ON-delay (AV) operating modes possible A1/A2 Control signal 1. Time accumulation: By separate actuation of the solonoid clutch B1/B2 Instantaneous contact and of the synchronous motor, elapsed time can be stored and/or 15/18; 25/28 various time segments accumulated. Delayed contact 15/16; 25/26 2.
