Alarm output/remote control unit (option)
About alarm outputs :
(1) Alarms can be set at 4 points in each channel and alarm outputs are provided as an option for up to
a maximum of 12 points.
(2) When an alarm is detected, the relevant terminals are shorted.
Relay contact capacity 240V/3A AC, 30V/3A DC (resistive load), 1a contact

Note:
If lamps are used on the outside, insert a resistor to prevent surge current. Also, if relays or
solenoids are used, insert elements for contact protection (diodes, surge killers, etc.)
About remote control inputs
(1) This performs the functions 'Recording operation start/stop', 'Two-stage changeover of recording
paper speed' and 'Data (instantaneous value) print-out' in response to contact signals from outside
the instrument.
(2) There are separate wiring terminals for the different functions.
(DI1) Record start .................. Recording starts when the contact is closed and
stops when the contact is open.
(DI2) Chart speed change ...... The chart speed is the remote mode speed when
the contact is closed and the normal operation
speed when the contact is open.
(DI3) Data print ...................... Print-out starts when the contact is closed and
goes on right to the end even if the contact is
opened partway through the print-out. If you
wish to stop print-out partway through, press the
LIST key on the front panel.
Note 1: As the external control unit is not insulated, use it with interposition of an external relay.
External contact capacity 12V DC/0.05A 1a contact
Note 2: Operations effects by the external control unit and the front panel switches are as in the table
below. (A - in a box of the table indicates that no effect at all is had on the main unit operation.)
Note 3: When using the message print function or alarm latch function, the meaning of control input is
different. Refer to "7.10 List print-out setting" and "9.3 Alarm latch specification".
