Instruction Manual
Detailed Version
Please ensure that this instruction manual is given to the final user of the instrument.
Preface
Thank you for purchasing Shimaden products. Please check that the delivered product is the correct item that you ordered. This instruction manual is meant for
those who will be involved in the wiring, installation, operation and routine maintenance of the SD17 series, and describes about cautions, mounting, wiring,
functions, and operation. Please observe the contents, and always keep the manual close at hand when handling this instrument.
The following headings give a description of matters requiring user attention concerning safety, damage to machines and equipment, additional explanations and
commentaries are described under the following headings.
• The SD17 Series digital indicator are designed for industrial use to control temperature, humidity and other physical values. Do not apply this instrument to
other objects in a way that may cause grave effects on human safety.
• In using this product, be certain to house it, for example, in a control panel, so that the terminals cannot come into contact with personnel.
• Do not take this instrument out of its case or put your hand or any conductor inside the case. Such conduct may lead to an accident that endangers life or
causes serious injury due to electric shock.
• To avoid damage to the connected equipment, facilities or the product itself due to a fault of the product, safety countermeasure must be taken before usage,
such as proper installation of the fuse and the overheating protection device.
• An alert symbol is printed on the terminal nameplate attached to the case. It warns not to touch the electrical charging parts when the power is being
supplied, so as to avoid the risk of electrical shock.
• Install a switch or breaker on the external source power circuit connecting to the source power terminal as a means to shut down the power.
The switch or breaker should be installed adjacent to the instrument in a position that allows the operator easy access.
• Regarding the fuse:
Since this instrument has no built-in fuse, make sure to install a fuse in the electric circuit connecting to the source power terminal.
Install the fuse in a position between the switch or breaker, and the instrument and attach it to the L side of the source power terminal.
Fuse Rating: 250V AC 1.0A/Time-lag (T) or Medium Time-lag (M)
• The load of voltage and current to be applied to the output terminal (analog output) and the alarm terminal must be within the rated range. If the range is
exceeded, the instrument will overheat causing the risk of the instrument being damaged and its life reduced.
As for the rating, please refer to "11. Specification."
The unit connected to the output terminal should conform to the requirements of IEC61010-1.
• Do not apply over-rated voltage or current to the input terminal. That will cause the risk of the instrument being damaged and its life reduced.
As for the rating, please refer to "11. Specification."
In case the input type is voltage (mV or V) or current (4 - 20mA), the unit connected to the output terminal should conform to the requirements of
IEC61010-1.
• Take care to prevent metal or other foreign matter from obstructing the ventilating hole for heat radiation. It will cause damage to the instrument and may
even result in fire.
• Do not block the ventilating hole. Also avoid dust accumulation. Any rise in temperature or insulation failure may result in a risk of the instrument being
damaged and its life reduced. As for the clearance space for installing the instrument, refer to "2-3 External dimensions and panel cutout."
• Repeating withstanding tests on voltage, noise, surging may lead to the deterioration of the instrument, so please be careful.
• Strictly refrain from remodeling and using the instrument improperly.
• It takes 30 minutes to display the correct temperature after applying power to the digital Indicator. (Therefore, turn the power on more than 30 minutes prior
to the operation.)
• To ensure safety and maintain the functions of this device, do not disassemble this device. If this device must be disassembled for replacement or repair,
contact your dealer.
• This device is designed for mounting on the panel. Only the device mounted on the front of the panel facing outward is of protection class of IP66. Do not
use for the device not facing outward or in environment where water or solids in excess of IEC60529 may get inside.
