Product Information

Transparent Guide LCD Digital Timers
The Transparent Guide LCD Digital Timers are electronic timers that can be used in various industrial applications. They have a transparent front panel that allows users to see the display clearly. The timers have a fail-safe device that can be installed when using the unit with machinery that may cause serious injury or substantial economic loss, such as nuclear power control, medical equipment, ships, vehicles, railways, aircraft, combustion apparatus, safety equipment, crime/disaster prevention devices, etc.

The unit has a compact design and can be installed on a device panel. It is important to follow the instructions provided in the manual while installing and using the unit to prevent any damage or injury. Users are advised not to connect, repair or inspect the unit while connected to a power source. The unit should be installed in a place where there is no possibility of flammable/explosive/corrosive gas, high humidity, direct sunlight, radiant heat, vibration, impact or salinity.

Users should check the connections before wiring and use the unit within the rated specifications to prevent any damage or injury. The unit cannot be disassembled or modified. Users should use a dry cloth to clean the unit and avoid using water or organic solvent. Keeping the product away from metal chip, dust, and wire residue is also essential to prevent any damage or fire.

Product Usage Instructions

The Transparent Guide LCD Digital Timers have different functions that users can use as per their requirements. The following are the product usage instructions:

1. Install the unit on a device panel and make sure to use a fail-safe device while using it with machinery that may cause serious injury or substantial economic loss.
2. Check the connections before wiring and use AWG 20 (0.50 mm2) cable or over, and tighten the terminal screw with a tightening torque of 0.74 to 0.90 N m.
3. Use the unit within the rated specifications and do not disassemble or modify the unit.
4. Use a dry cloth to clean the unit, and keep the product away from metal chip, dust, and wire residue.
5. The unit has different keys that are used for different functions. The [RST] key is used to initialize the progressing time and output return. The [MD] key is used to enter RUN mode, and the [] key is used to shift to the next parameter in parameter setting.
6. Users can use the UP / DOWN keys to select the time unit or mode of time progressing, and use the [] key to move the digit when changing the setting value.
7. The unit also has a key lock function that shows the key lock status.

   Failure to follow this instruction may result in fire or product damage.

Cautions during Use

• Follow instructions in ‘Cautions during Use’. Otherwise, it may cause unexpected accidents.
• When supplying or turning off the power, use a switch or etc. to avoid chattering.
• Install a power switch or circuit breaker in the easily accessible place for supplying or disconnecting the power..
• In order to block peripheral current, use isolation transformer which of secondary part is not grounded to supply power to the external input device
• Do not connect two or more timers with only one input contact or transistor simultaneously.
• Keep away from high voltage lines or power lines to prevent inductive noise. In case installing power line and input signal line closely, use line filter or varistor at power line  and shielded wire at input signal line.
• Do not use near the equipment which generates strong magnetic force or high  frequency noise.
• This unit may be used in the following environments.
  • Indoors (in the environment condition rated in ‘Specifications’)
  • Altitude max. 2,000 m
  • Pollution degree 2
  • Installation category II
