Precautions for use:
Action time setting
• When setting the operating time, do not turn the knob beyond the scale range. When the time limit needs to be more accurate, please measure the operating time before use and adjust it with the knob.
• The repeating accuracy value of the analog timer operating time is% of the maximum scale time, so even if the setting time is changed, the absolute value of the dispersion will not change. Therefore, please select the time specification and use it as close as possible to the maximum scale.
• If the setting of the analog timer is changed within the set time, the following actions are performed.
Control output
· Please use the control output contact within the rated value range. Please note that if used above the rated value, the contact life will be significantly shortened.
• When switching a small load, check the minimum applicable load stated in each product.
· The life of the contact for control output will vary greatly with the switching conditions. When using, please be sure to confirm on the actual equipment under actual use conditions,
Use within the number of switches with no problem in performance. If you continue to use it in a state of degraded performance, it will eventually cause insulation damage between the circuits and burnout of the relay itself.
· Please avoid the following connections, otherwise it may cause a short circuit between different pole contacts inside the timer.
About the power supply
• Apply power supply voltage quickly through the contacts of switches, relays, etc. If the voltage is applied slowly, the power supply will not reset or the timer time will stop.
• The time when the power is turned on is short. When the inrush current occurs, the timer does not start due to insufficient capacity of the power supply. Use a power supply with sufficient capacity.
For the inrush current value of each model, please refer to page 1490.
· If the power connection is used under AC power, it can be connected to the specified 2 terminals regardless of polarity, but please pay attention to the polarity under DC power.
• In addition, please note that when a voltage different from the rated voltage is applied, or when the wiring is incorrectly connected or the polarity is reversed in the DC specification, it may cause malfunction, abnormal heat generation, and burnout.
· If it is a DC power supply, please set it to the specified ripple rate.
Note. Please refer to the ripple rate of each timer.
· For the application of external pulse voltage between the power terminals, the pulse voltage and current test (JEC-210) established by the Japan Electrical Engineering Institute is used as the standard.
Confirm with a standard waveform of ± (1.2 × 50) μs, but if a pulse voltage exceeding this value occurs, use a surge absorber.
If surge or noise is superimposed on the external power supply, it will cause damage or malfunction of internal components. Therefore, it is recommended that you use components for surge absorption while confirming the circuit waveform.
The surge and noise are different, and the effects of the components are also different. Please check with the actual device.
• When the power is off, do not apply residual voltage or induced voltage.

● Suidhich
When setting with the key switch, do not use claw-shaped or sharp-headed tools. If you use a claw-shaped or sharp-headed tool, the key may be damaged.
● Other
• When carrying out the voltage test, pulse voltage test, insulation resistance measurement, etc. between the electrical circuit and the non-charged metal part with the control panel installed,
In order to prevent the deterioration and damage of the internal circuit of the timer when some parts of the machine inside the control panel and the parts have withstand voltage or poor insulation
① Please disconnect the timer from the circuit. (Unplug the socket from the timer, remove the wiring, etc.) or
②Short all terminals of the terminal section.
· When the device without contact output (such as proximity switch, photoelectric switch or solid state relay, etc.) directly drives the timer,
The timer may malfunction due to the leakage current of the non-contact device. Please confirm it before use.
• Please remove the wiring when replacing the battery. Risk of electric shock if touching high voltage applied parts.
• When switching inductive loads, in order to prevent malfunction or destruction of the timer, install a surge absorbing element.
Regarding the surge absorption element, a diode can be installed in the DC circuit, and a surge absorber can be used in the AC circuit.

A timer is a device that uses a specific principle to measure time. Timers can be used to help you solve these problems. The operation interface is simple and easy to use, and provides basic timing control functions, including: start timing, stop timing, continue timing, the operation interface is simple and easy to reset, adjust the timing.

The types of modern timers include electromagnetic dot timers, spark timers, stick timers, parking timers, reaction timers, amplification timers, and windows timers. Electromagnetic strike timers and spark strike timers are the most common.
Electromagnetic dot timer is a timing instrument using AC power. Its working voltage is 4-6V, the frequency of the power supply is 50Hz, and it strikes every 0.02s. Working principle: When the coil of the electromagnetic timing timer is energized, the coil generates a magnetic field, the vibrating piece in the coil is magnetized, and the vibrating piece moves upward or downward under the action of the magnetic field of the permanent magnet, because the direction of the alternating current changes every cycle Twice, therefore, the magnetic pole of the magnet after the magnet is changed, and the direction of the permanent magnet's force on it must also be changed. When the diaphragm is under the downward force, it is dotted once, when the diaphragm is under the upward force. Dot, so do it once in a cycle of AC, that is, the time interval between every two points is equal to the cycle of AC.
The EDM timer is a timing instrument that uses spark discharge to make small holes in the paper tape to show dots. It uses 220V AC voltage. When the frequency is 50Hz, it hits every 0.02s. When the EDM timer works The resistance to the guided exercise is relatively small, and the test error is smaller than that of the electromagnetic timing timer. Working principle: The spark sparking timer is a timing instrument that uses spark discharge to make the toner print ink dots on the paper tape to show the traces. Connect the 220V power supply to the spark sparking timer, press the pulse output switch, and time The pulse current sent by the device is connected to the discharge needle and toner tray of the positive electrode to the tray shaft connected to the negative electrode, and a spark discharge is generated, so a series of points are punched on the paper tape, and it is discharged once every cycle of the alternating current, so The interval between hitting points of the EDM timer is equal to the period of alternating current.

The input method of OMRON PLC timer is to input BCD code in the timer. If it is 100ms BCD type, if you want to set 3 seconds, you can directly type # 30 in the setting value. # 10 represents the time value of 1 second.
Omron PLC uses programmable memory to store internal instructions for performing logical operations, sequential operations, timing, counting, and arithmetic operations, and can control various types through digital or analog input and output Machinery or production process.
In the input sampling stage, the programmable logic controller sequentially reads all input states and data in a scanning manner and stores them in the corresponding unit in the I / O image area. After the input sampling is completed, it shifts to the user program execution and output refresh phase.
In these two stages, even if the input status and data change, the status and data of the corresponding unit in the I / O image area will not change.
The classification of PLC timer:
1. On-delay timer: On-delay timer is the most common and basic timer in various PLCs. This timer is called SD timer in SIEMENS PLC.
2. Off-delay timer: This timer has no delay effect when the input condition 00000 is ON, and only has a delay effect when the input condition 00000 is OFF. In SIEMENS PLC, it is called SF type timer.
3. Hold-up on-delay timer: This timer generates a latch function when the input condition 00000 is ON, even if the input condition 00000 becomes OFF again, the input condition is still regarded as ON.
When the current value of the timer is equal to the set value, the timer acts. This timer is called SS type timer in SIEMENS PLC. The setting value can be a constant or a channel number. When it is a constant, it must be a BCD code. Add # in front; when it is a channel number, the number in the channel must also be a BCD code.
Omron PLC timer time setting range is 0 ~ 9999.9 seconds.
To set 3 seconds

The internal structure of the mechanical timer principle is mainly composed of three parts:
The first part is the power component, which is a one-way mechanism from the mainspring and the mainspring, so that when it is manually twisted, it can only be tightened, not loose. Tightening the mainspring provides the power for the entire system.
The second part is the release part. A series of gear shifts increase the number of rotation cycles when the mainspring relaxes. At the end of the gear train are escapement wheels, escape pawls and hairsprings to ensure that the speed of the gear train rotates under the drive of the spring. The hairspring has a device for self-adjusting the length of the hairspring, to adjust the frequency of the escapement claw swing, to ensure that the gear rotates at the set speed, will not loosen the tightened spring at once, and is not affected by the tightness of the spring This causes a change in speed.
The third part is the timing trigger device, which makes an electrical signal or mechanical signal after a gear in the gear train turns to a certain angle to stop the power supply or ring the bell.
The three parts work together. When the timer is turned to a certain scale, two things are actually done. One is to tighten the mainspring to provide power to start the timer. The other thing is to set the scale. The trigger position of the trigger mechanism is determined.
Then under the control of the escape wheel, the entire structure slowly releases the power of the mainspring, and the gears at all levels start to rotate at a constant speed until the mechanism is triggered.
