Precautions
J
OPERATING ENVIRONMENT
•
Operate the Controller within the rated ambient operating
temperature, ambient operating humidity, and storage tem-
perature ranges.
•
Use the Controller according to the vibration resistance,
shock resistance, and enclosure ratings.
•
Do not install the Controller in places with corrosive gas or
excessive dust.
•
Do not install the Controller near machines generating high-
frequency noise.
J
MOUNTING
•
The dimensions of the Controller conform to DIN 43700.
•
Recommended panel thickness is 1 to 8 mm.
•
Mount the Unit horizontally.
J
CONNECTION
•
To reduce inductive noise influence, the lead wires connect-
ing the input type to the Controller must be separated from
the power lines and load lines.
•
Use the specified compensating conductors for thermocou-
ples. Use lead wires having a small resistance for platinum
resistance thermometers.
J
CONNECTION EXAMPLE
•
Wire the terminals of the Unit using solderless terminals.
•
The tightening torque applied to the terminal screws of the
Unit must be approximately 0.78 N
S
m or 8 kgf
S
cm.
•
Use the following type of solderless terminals for M3.5
screws.
7.2 mm max.
7.2 mm max.
J
OPERATION
•
The alarm outputs of a model with an alarm function may not
turn ON correctly when the model malfunctions. The use of
alarm equipment with the Controller is recommended.
•
The parameters and internal switch are set before shipping
so that the Unit will function normally. Change the settings of
the parameters and internal switch according to the
application if necessary.
•
After power has been supplied to the Controller, several se-
conds are required until the relay is turned ON. Consider this
time delay when designing sequenced circuits which
incorporate a Controller.
•
Do not use excessive force when removing the internal
mechanism from the housing. Protect the internal connector
or electronic parts of the Unit from shock.
•
Protect against static discharge when changing the settings
of the internal switch. Changing the settings on a grounded
conductive mat is recommended.
•
When connecting the control output board to the Tempera-
ture Controller or Process Controller, make sure that the
control output board is the appropriate type, or the system
may malfunction.
