POINTS OF CAUTION
■ CONFORMITY WITH EU DIRECTIVE
• Use MECHATROLINK-II network cable with core (Yasu-
kawa Controls Model JEPEC-W6003-x-E) or equivalent
for the network.
• Be sure to earth FG terminal.
• The actual installation environments such as panel con-
figurations, connected devices and 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 CE conformity.
■ POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
24V DC rating: 24V ±10%, approx. 130mA
■ GENERAL PRECAUTIONS
• Before you remove the unit or mount it, turn off the power
supply and input signal for safety.
■ ENVIRONMENT
• Indoor use
• When heavy dust or metal particles are present in the air,
install the unit inside proper housing with sufficient ven-
tilation.
• 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 0 to 55°C (32
to 131°F) with relative humidity within 30 to 90% RH in
order to ensure adequate life span and operation.
■ 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 sup-
plied, however, a warm up for 10 minutes is required for

- Page 10 R7ML-LC2 ■ AUTOMATIC ZERO CORRECTION Set the offset input value. Perform automatic zero correction setting after Zero/Span adjustments. The procedures are as follows. 1) Apply desired offset input value to the sensor. 2) Set “1” to Automatic zero correction bit. When the offset is completed, LED0 for Input 0 or LED8 for Input 1 turns on. 3) After checking the LED, set “0” to Automatic zero correction bit. ■ ZERO ADJUSTMENT Adjust input zero point. The procedures are as follows. 1) Apply 0% load to the sensor. 2) Set “1” to Zero adjustment bit. When the adjustment is completed, LED1 for Input 0 or LED9 for Input 1 turns on. 3) After checking the LED, set “0” to Zero adjustment bit. ■ SPAN ADJUSTMENT (with actual load) Adjust input span point with the actual load. The procedures are as follows. 1) Apply actual 100% load to the sensor. 2) Set “1” to Span adjustment bit. When the adjustment is completed, LED2 for Input 0 or LED10 for Input 1 turns on. 3) After checking the LED, set “0” to Span adjustment bit. ■ LOAD COEFFICIENT Adjust input Span point by setting load coefficient without applying 100% actual load. The followings are an example of adjustment with 20 % load. 1) Apply 20% load of the actual load to the sensor. 2) Set 2000 (decimal) to Input set data area. 3) Set “1” to Span adjustment bit. When the adjustment is completed, LED2 for Input 0 or LED10 for Input 1 turns on.
