School Bell Control Instrument 40 Groups DIN Timer Switch

Product Description

1 Purpose and scope of application
     NKG-5 time-controlled switch is mainly used as a time control element in circuits with AC 50Hz, rated control power supply voltage to 220V and below and DC power supply 24V and below, according to a predetermined procedure to turn on or off the circuit. This product is a cycle delay switch. The cycle mode can set a group of cycle on and cycle off time. When working, the cycle action is performed according to the set time.
2 Main technical parameters
2.1 Rated control power supply voltage: DC24V AC220V.
2.2 Conventional heating current: 16A (resistive load 16A).
2.3 Rated working current (Ie): AC-15.220V 3A.
2.4 Timing error: ≤5ppm.
2.5 Number of cyclic timing groups: 1 group.
2.6 Working temperature range: -20 ºC ~ 60 ºC.
2.7 Cycle time: adjustable from 1 second to 99 hours, 59 minutes and 59 seconds.
2.8 Installation method: device type, rail type.
4.2 The specific setting steps are as follows:
4.2.1 Timing parameters (cycle on / off time) setting
4.2.2.1 Press the "MD" key in the current clock state to enter the working time setting state, at this time, 1on is displayed in the lower left corner of the screen, as shown in Figure 4.
4.2.2.2 1ON (the first group of cycles on) time setting: press "" to enter second, minute and hour setting in sequence, at this time the setting bit flashes, press "" "" to set the delay time 5 shows.
4.2.2.3 Press the "MD" key to enter the 1OFF (the first group of cyclic off) time setting, set the 1OFF time as in step 4.2.2.2, as shown in Figure 6.5 matters needing attention
5.1 Before using the product, push the blue buckle on the bottom one step.
5.2 The incoming line of this switch can only be connected to DC24V power supply, do not connect to other power supply.
5.3 This product will be automatically set to start the cycle countdown after power on.
5.4 Press and hold the "" "" key for quick setting.
5.5 Standby for 1 minute without any key press, the product will automatically exit the setting state.
5.6 Short-circuit the A3 and A4 terminals to reset the product. The cycle time after reset is 15 seconds on and 5 seconds off by default.
5.7 The shelf life of this product is 18 months. If the product fails after the shelf life, the company still bears the obligation of maintenance, but the user must bear the corresponding cost.
