■ ENVIRONMENT
• Indoor use.
• When heavy dust or metal particles are present in the air, install the unit inside proper housing with sufficient 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 -5 to +55°C
(23 to 131°F) with relative humidity within 30 to 90% RH in order to ensure adequate life span and operation.
■ MODEL NO.
Confirm Model No. marking on the product to be exactly what you ordered.
■ INSTRUCTION MANUAL
This manual describes necessary points of caution when you use this product, including installation, connection and basic maintenance procedures.
■ WIRING
• Do not install cables close to noise sources (relay drive cable, 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.
■ 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.
POINTS OF CAUTION
■ CONFORMITY WITH EC DIRECTIVES
• This equipment is suitable for Pollution Degree 2 and Installation Category II (transient voltage 2500V). Basic 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.
• Altitude up to 2000 meters.
• The equipment must be mounted inside a panel.
• Insert a noise filter for the power source connected to the unit. TDK-Lambda Noise Filter Model RSAN-2006 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.
• The actual installation environments such as panel configurations, connected devices, connected wires, may affect the protection level of this unit when it is integrated in a panel system. The user may have to review the CE requirements in regard to the whole system and employ additional protective measures to ensure the CE conformity.
• Install lightning surge protectors for those wires connected to remote locations.
■ POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and confirm its operational range as indicated below:
100 – 240V AC rating: 85 – 264V, 47 – 66 Hz, approx. 10VA
12 – 24V DC rating: 10.8 – 26.4V, approx. 3.5W
110V DC rating: 85 – 150V, approx. 3.5W
■ GENERAL PRECAUTIONS
• Before you remove the unit from its base socket or mount it, turn off the power supply and input signal for safety.

MXCB
FUNCTIONS
■ DEFAULT SETTING
• MXCB Used Independently
In normal operating mode, the MXCB responds to UP/
DOWN signals from the computer in the preset ramp rate.
If the computer fails, this will be detected as a “STOP” command and output will be held at the value prior to the breakdown. You can increase the output signal by closing across the terminals 9 – 11, and decrease it by closing 10 –
11. The output responds in the preset ramp rate.

• MXCB Used in Combination with ST/STL
In normal operating mode, the MXCB responds to UP/DOWN signals from the computer in the preset ramp rate. If the computer fails, the “STOP” command will override computer output and put the unit in the manual operation mode by the ST/
STL. Using the top-mounted UP or DOWN key, output can be increased or decreased in the preset ramp rate.
Output signal value can be read on the top-mounted indicator.
For more precise control, use the monitor terminals. Also the computer input can be overridden with the AUTO/MANUAL selector on the Soft-Terminal. This is useful when you need to change the output quickly during automatic operation by the computer control.
CHECKING
1) Terminal wiring: Check that all cables are correctly connected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
7 – 8 with a multimeter.
3) Output at STOP signal OFF: The output does not respond to UP (3 – 6) or DOWN (4 – 6) signals.
4) Output: Check that the load resistance meets the described specifications.
MAINTENANCE
Regular calibration procedure is explained below:
■ CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0% and
100% input signal. Check that the output signal 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 “ADJUSTMENT PRO-
CEDURE” explained earlier.
ADJUSTMENT PROCEDURE
This unit is calibrated at the factory to meet the ordered specifications, therefore you usually do not need any calibration.
For matching the signal to a receiving instrument or in case of regular calibration, adjust the output as explained in the following.
■ HOW TO CALIBRATE THE OUTPUT SIGNAL
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) Reset all setting.
2) Turn the unit into Program mode.
3) Set the PV display to show 0.0 and adjust the output to
0% (ITEM 06).
4) Set the PV display to show 100.0 and adjust the output to
100% (ITEM 07).
5) Set the PV display to show 0.0 again and check the output.
6) When the output value is changed, repeat the above procedure 3) – 5).
7) Return the unit into Monitor mode.
