4 Using the External Input and Output
When using the external input and output functions, use the external input and output cables provided with the remote controller.
(5 wire cable for input and 4 wire cable for output are provided.)
1. External signal input function
(1) External Input
Emergency stop/Normal, ON/OFF and Prohibit/Permit local remote controller operation control can be applied to all units
being controlled by inputting the no-voltage contact signal from an external source.
No.
External input signal functions
Do not use external input
1
Change between Emergency stop/Normal.
All units will stop with the external input,and all operations of this unit,other system controllers and
2
local remote controller will be prohibited.
Set ON/OFF
All units will turn ON/OFF according to the input state. ON/OFF operations using this unit and the
3
local remote controller will be prohibited when using this function.
Set ON/OFF and Prohibit/Permit.
All units are started or stopped, or all local remote controller operations are prohibited according to
4
the input state. When prohibit is input, the local remote controller's ON/OFF, operation mode, set
temperature and filter reset operations will be prohibited. Operation with this system will be enabled.
NOTE :
For System remote controller and Schedule timer
* If the SW3-4 "operation prohibit setting changeover" is set to "OFF (disable)", use is possible only for emergency stop.
* If the SW3-5 "operation prohibit range setting changeover" is set to "ON (including system controller), operations of the local remote
controller and other system controllers will be prohibited by the prohibit input. If set to "OFF (only local remote controller)", operation
of only the local remote controller will be prohibited. (When the level "emergency stop" or "ON/OFF" is input, operation of the other
system controllers will also be prohibited regardless of the switch setting.)
For ON/OFF remote controller
* All units are stopped when emergency stop is input, and ON/OFF operations of this unit, other system controllers and local remote
controller will be prohibited.
* Only ON/OFF of the local remote controller will be prohibited with the prohibit input.

•
The relays and extension cables, etc. must be prepared separately at the site.
•
Use a no-voltage contact and minute load relay (minimum application load 5VDC-1mA).
•
The length of the connection cable extension should not exceed 10m. (Use a cable of 0.3mm
•
Cut of the cable not being used close the connector and properly insulate the cut off ends with tape or the like.

For pulse signal
* Operation will continue even if a ON signal is input during operation. (This also applies to OFF, prohibit and enable).
* If the local remote controller is prohibited, ON/OFF, operation mode, temperature and filter reset operations using the local
remote controller will be prohibited. (Only ON/OFF are prohibited for the ON/OFF remote controller.)
* Set the pulse duration (contact ON time) to 0.5sec or more.
