UK/USA Precautions for Safe Use

Please comply strictly with the following instructions which are intended to ensure safe operation of the controller. (1) (1) Make sure the proper product is specified for the application.

(2) For correct use, do not subject the timer to the following conditions.

• Dramatic temperature fluctuations • High humidity or where condensation may occur • Severe vibration and shock • Where excessive dust, corrosive gas, or direct sunlight may be present • Where there is danger of splashing of water, oil or any chemicals (3) Store the Timer within the rated ranges given for the Timer model you are using. If the Timer is stored (3) 10 below −10°C, allow it to warm up for three hours at room temperature before turning ON the power supply. (3) 10 (4) Mounting the Time Switch side-by-side may reduce the life expectancies of internal components. H3CR-H8RL (5) Use the Timer within the ambient operating temperature and ambient operating humidity ranges

given for the Timer model you are using.

(6) Separate the Timer from any sources of excessive static electricity, such as forming materials

(5) (6) and pipes carrying power or liquid materials.

(6) (7) Maintain the variations in the power supply voltage to within the specified allowable range.

(7) (8) If a voltage that exceeds the rating is applied, internal components may be destroyed.

(8) (9) Wire all terminals correctly.

(9) (10) Do not wire the terminals which are not used.

(8) (11) Install and clearly label a switch or circuit breaker so that the operator can quickly turn OFF the power supply.

(9) (11) OFF (12) The exterior of the Timer may be damaged by organic solvents (such as thinners or benzene), (10) strong alkali, or strong acids. (13) Confirm that the power and output indicators are operating normally. Depending on the

(11) OFF (12)

operating environment, the indicators and plastic parts may deteriorate faster than expected,

(12) · causing the indicators to fail. Periodically perform inspections and replacements.

(13) / LCD LCD/ (13) / LCD (14) When disposing of the Timer, observe all local ordinances as they apply.

LCD/ (15) When using the Timer in an area with excessive electronic noise, separate the Timer and input

device as far as possible from the noise sources. It is also recommended to shield the input

(14) signal wiring to prevent electronic interference.

(15) (16) Cleaning

Do not use paint thinner or the equivalent. Use standard grade alcohol to clean the product. (16) (17) Do not change the time range while the Timer is in operation, otherwise the Timer may malfunction. Be sure that the Timer is out of operation before changing the setting. (18) Power supply connection

(17) Use a DC power supply having a ripple factor of 20% or less and supplying a mean voltage

(1) that is within the rated operating voltage marked on the timer. (18) Make sure that the supply voltage is applied to the timer all at once, using contacts such as of a switch or relay. Otherwise, the timer may not be able to perform power reset or its set time may be up when it should not.

(19) Please do not exceed the voltage rating marked on the timer. If voltage other than the rated voltage is applied, the internal components may be damaged.

(20) Input connection (19) When connecting the contact or transistor for external input signal to the input terminals of the timer, pay

(4) attention to the following points to prevent short-circuiting of the transformerless power supply. DC 20 If a relay or a transistor is connected as an external signal input to a Timer (ex. H3CR-A),

(20) whose power supply terminal is a common terminal for input signal, and the H3CR-H,

short-circuit current is generated. Be sure to input for each Timer from an independent isolated relay or isolate the power supply

(5) of either of those Timers. (6) For the power supply of an input device, use an isolation transformer(*2), of which the primary

H3CR-A H3CR-H H3CR and secondary windings are mutually isolated and the secondary winding is not grounded. (*3)

(21) To the input signal terminals of the Timer, an appropriate input is applied when the specified (*2) H3CR-A H3CR-H terminals are short-circuited. Do not attempt to connect any input terminal to any terminal other than the input terminal or to

apply voltage across other than the specified input terminals.

(21) Otherwise, the internal circuit of the Timer may be damaged.

The H3CR-H has a large inrush current. Provide sufficient power supply capacity. (7) If the power supply capacity is too small, there may be delays in turning ON the output. The H3CR-H uses a latching relay for the output. Shock, such as dropping the H3CR-H

H3CR-H ON

during shipment or handling, can cause the output contacts to reverse to the neutral position.

H3CR-H H3CR-H

Check the output status with a tester before using the H3CRH. (22) As the H3CR-H has a high impedance circuit, it may sometimes not be reset by the interference

H3CR-H

(22) H3CR-H of induced voltage. To prevent such trouble, wire the lead as short as possible and avoid laying wires in parallel with power lines. (23) In case the induced voltage exceeds 30% of the rated voltage (10% for DC type), connect a CR filter

(23) 30% 10% (8) H3CR-H (C=0.1 μF, R=120 Ω approx) or a bleeder resistor across the power supply terminals of the timer.

CR C = 0.1 μF, R = 120Ω) Also, when there is residual voltage across the power supply terminals, connect a bleeder

(24) H3CR-H resistor in the same manner.

(9) 30 DC CR (24) Do not use the H3CR-H under the conditions below since they may cause malfuntion.

C=0.1μF R=120Ω Time expiration operation within 3 seconds max. repeat frequency.

Force-reset within 3seconds max. repeat frequency.

(25) EN/IEC (10) H3CR-H (25) EN/IEC Standard Compliance

EMC Refer to the datasheet for the H3CR for cable selection and other conditions for compliance class A with EMC standards. (11) EN/IEC This is a class A product. In residential areas it may cause radio interference, in which case EMC the user may be required to take adequate measures to reduce interference. The power supply terminals and input terminals are not isolated. There is basic insulation class A between the power supply terminals and output terminals. IEC60664 If double or reinforced insulation is required, use the double or reinforced insulation defined in IEC 60664 that is suitable for the maximum applied voltage for the clearance, solid insulation, and other factors.
