■OPERATING MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection, ba-
sic maintenance procedures, and detailed operations.
The 54UL is programmable either by using the front control
buttons or the PC Configurator Software. For detailed in-
formation on the PC configuration, refer to the PMCFG us-
ers manual. The XIF files and the PMCFG PC Configurator
Software are downloadable at M-System’s web site.
http://www.m-system.co.jp
Availability of certain functions explained in this manual
depends upon hardware options and firmware versions.
Those limited ones are identified with the following mark-
ings.
MARKING LIMITATION
DO Discrete input option
DI Discrete input option
3P4W 3-phase / 4-wire system option
3.00 Ver.3.00 or later versions
POINTS OF CAUTION
■AUXILIARY POWER SUPPLY RATING & OPERATIONAL
RANGE
• Locate the auxiliary power supply rating marked on the
product and confirm its operational range as indicated
below.
100 – 240V AC rating: 85 – 264V AC, 50/60 Hz, < 8VA
110 – 240V DC rating: 99 – 264V DC, < 4W
■GENERAL PRECAUTION
• Before you remove or mount the unit, turn off the power
supply and input signal for safety.
■ENVIRONMENT
• Indoor use.
• Do not install the unit where it is directly exposed to rain,
water droplets or sunlight.
• 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 -10 to +55°C
(14 to 131°F) with relative humidity within 90% RH in
order to ensure adequate life span and operation.
• Contrast of the LCD screen depends upon viewing angles.
Choose the height and angle where it is the most legible.
• Do not apply physical impact to the front face.
• To ensure the designated ingress protection, insert the
gasket before attaching the mounting brackets.
• When using the mounting brackets, remove the mounting
screws and turn back the gasket as shown below.
Mounting Bracket
Panel
Gasket
Hole
■WIRING
• Wiring to the unit must be conducted by qualified service
personnel.
• 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
satisfying complete performance described in the data
sheet.
• Altitude up to 2000 meters.
• The equipment must be mounted inside a panel.
LIGHTNING SURGE PROTECTION
M-System offers a series of lightning surge protector for
protection against induced lightning surges. Please contact
M-System to choose appropriate models.
