BEFORE USE ....
Thank you for choosing M-System. Before use, please check
contents of the package you received as outlined below.
If you have any problems or questions with the product,
please contact M-System’s Sales Office or representatives.
■PACKAGE INCLUDES:
CT alarm (body + base socket + CT protector) ..................(1)
■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.
POINTS OF CAUTION
■CONFORMITY WITH EU DIRECTIVES
• This equipment is suitable for Pollution Degree 2, Meas-
urement Category II (output, transient voltage 2500V)
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 require-
ments.
• 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 RSNA-2006 or
equivalent is recommended.
• The equipment must be installed such that appropriate
clearance and creepage distances are maintained to con-
form to CE requirements. Failure to observe these re-
quirements may invalidate the CE conformance.
• The actual installation environments such as panel con-
figurations, connected devices, connected wires, may af-
fect 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 conform-
ity.
• Install lightning surge protectors for those wires connect-
ed 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,
4.6VA at 100V AC
5.9VA at 200V AC
6.8VA at 264V AC
24V DC rating: 24V ±10%, 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.
■CT PROTECTOR
• Temperature of the CT Protector may rise if the signal
conditioner body is left unplugged from the base socket.
Be careful not to get burned when you need to touch it.
■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.
■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
satisfying complete performance described in the data
sheet.

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
7 – 8 with a multimeter.
3) Input: Check that the input signal is within 0 – 100% of
the full-scale.
Be sure to short the secondary side of CT or turn off the
current at its primary side for preventing the CT from
burning when the cables are to be disconnected from in-
put terminals of the base socket.
4) Alarm operations: Check the alarm operations referring
to the figure below.
5) Output load: Check that the output load is 380 V AC /
120 VA or 125 V DC / 30 W (≤ 0.5 A for CE) at the maxi-
mum. For maximum relay life with inductive load, exter-
nal protection is recommended.

Trip Operation in Power Failure
• Output code 2: All relays turn off.
• Output code 3: All relays turn on.
• Output code 5: Terminals 1 –3, 9 – 11 turn on.
MAINTENANCE
Regular calibration procedure is explained below:
■CALIBRATION
Warm up the unit for at least 10 minutes.
• H (HH) Setpoint
Increase the input signal from a value lower than the set-
point and check that the relay trips at the H (or HH) set-
point within the setpoint accuracy described in the data
sheet.
• L (LL) Setpoint
Decrease the input signal from a value higher than the
setpoint and check that the relay trips at the L (or LL)
setpoint within the setpoint accuracy described in the
data sheet.
When the setpoints are shifted, please contact M-System’s
Sales Office or representatives.
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.
