M-System 48N DT Bargraph Indicating Alarm Instruction Manual
Below you will find brief information for Bargraph Indicating Alarm 48N 48NDT. This manual describes the installation, connection, and basic maintenance procedures for the 48N 48NDT. The product is designed for indoor use and must be mounted on a panel surface with appropriate ventilation. The product must be installed such that appropriate clearance and creepage distances are maintained to conform to CE requirements. Failure to observe these requirements may invalidate the CE conformance. The product is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required for satisfying complete performance described in the data sheet.

MODEL
■ REQUIREMENTS TO ENSURE IP65
• Observe the designated panel cutout size (31.5 × 138 mm).
• Single mounting only. IP65 is not ensured when the units are clustered side by side.
• The watertight packing included in the product package must be placed behind the front cover.
• The mounting bracket must be fastened tightly until they hit the panel.
• Confirm visually that the packing is not contorted or excessively run off the edge after installation.
■ WIRING
• Do not install cables (power supply, signal input and output) close to noise sources (high frequency line, etc.).
• Do not bind these cables together with those in which noises are present. Do not install them in the same duct.
■ INSTRUCTION MANUAL
This manual describes necessary points of caution when you use this product, including installation, connection and basic maintenance procedures.
POINTS OF CAUTION
■ CONFORMITY WITH EC DIRECTIVES
• This equipment is suitable for Pollution Degree 2 and Installation Category II. Reinforced insulation (signal input to output to power input: 300V) is maintained. Prior to installation, check that the insulation class of this unit satisfies the system requirements.
• The equipment must be mounted on a panel surface. Once mounted on a panel, take appropriate precautions to prevent operators to be exposed to the terminal block.
• Altitude up to 2000 meters
• Insert a noise filter for the power source connected to the unit. TDK-Lambda Noise Filter Model MZS-1206-33 or equivalent is recommended.
• The equipment must be installed such that appropriate clearance and creepage distances are maintained to conform to CE requirements. Failure to observe these requirements may invalidate the CE conformance.
■ TERMINAL BLOCK
• The terminal block is separable in two pieces. Loosen two screws on top and bottom of the terminal block to separate.
• Be sure to turn off the power supply, input signal and power supply to the output relays before separating the terminal block.

■ AND ....
• The unit is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required for satisfying complete performance described in the data sheet.
■ POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and confirm its operational range as indicated below:
AC rating: 85 – 264V, 50/60 Hz, approx. 5.5 – 8VA
DC rating: 24V ±15%, approx. 3.5W
■ ENVIRONMENT
• Indoor use
• If the unit’s environmental protection is compromised (e.g. when multiple units are to be mounted side by side) when heavy dust or metal particles are present in the air, install them inside an enclosure with a proper ventilation.
• Do not install the unit where it is subjected to continuous vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within -10 to +55°C
(14 to 131°F) with relative humidity within 30 to 90% RH in order to ensure adequate life span and operation.

■ USING BEZELS
Bezels are used when the unit needs to be adapted to an existing panel cutout. It is not required when the panel cutout size is as specified in the unit’s data sheet (31.5 × 138 mm).
Three types of bezels are selectable when ordering.
Standard type: Fits into M-System’s 48 Series’ panel cutout (38 × 139.5 mm)
Option /D type: Fits into DIN panel cutout
× 138 mm)
Option /F type: Fits into Fuji Electric PAJ, PAK, PBA,
etc, panel cutout (44 × 138 mm)
Slide the top and bottom parts of the bezel into the back of the front cover as shown below.
Bezel
When multiple units are to be clustered side by side, insert one bezel between two units as shown below.
• When mounting two or more indicators side by side:

■ HOW TO MOUNT THE UNIT ON A PANEL
1) Insert the unit into the panel cutout. The watertight packing must be in place to hold the unit. Do not remove it even when the protection is not required.
The IP65 front cover protection is effective only with single mounting, with the designated cutout size (31.5 ×138 mm).

CALIBRATION PROCEDURE
This unit is calibrated at the factory to meet the ordered specifications, therefore you usually do not need any calibration.
For matching the indication to a receiving instrument or in case of regular calibration, adjust the output as explained in the following.
■ HOW TO CALIBRATE THE OUTPUT INDICATION
Use a signal source and measuring instruments of sufficient accuracy level. Turn the power supply on and warm up for more than 10 minutes.
1) ZERO: Apply 0% input and adjust output indication to
0% following the procedure explained in “ADJUSTMENT
PROCEDURE.”
2) SPAN: Apply 100% input and adjust output indication to
100% following the same procedure.
3) Check ZERO adjustment again with 0% input.
4) When ZERO value is changed, repeat the above procedure 1) – 3).
MAINTENANCE
Regular checking procedure is explained below:
■ CHECKING
Warm up the unit for at least 10 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal. Check that the output indication for the respective input signal remains within accuracy described in the data sheet. When the output is out of tolerance, recalibrate the unit according to the “CALI-
BRATION PROCEDURE” explained earlier.
