Heating/Cooling control [option code: DT2]
The specification of Heating side is the same as that of OUT1.
OUT2 proportional band : 0.0 … 10.0 times OUT1 proportional band (ON/OFF action when set to 0.0)
OUT2 integral time
: The same as that of OUT1.
OUT2 derivative time : The same as that of OUT1.
OUT2 proportional cycle : 1 … 120 seconds
Overlap band/Dead band setting range:
Thermocouple, RTD inputs : –100.0 … 100.0 °C (°F)
DC current, DC voltage inputs : –1000 … 1000 (The placement of the decimal point follows the
selection)
Output: Non-contact relay output 0.3 A 250 V AC
Cooling action mode selection function:
One cooling action can be selected from Air cooling (linear characteristic), Oil cooling (1.5th power of
the linear characteristic) and Water cooling (2nd power of the linear characteristic) by key operation.
Serial communication [option code: CR5]
When this option is added, the option [SV2] cannot be added with it.
The following operations can be carried out from the external computer.
(1) Reading and setting of the main setting value, PID values and each setting value
(2) Reading of the input value and action status
(3) Change of the functions
Communication interface
: Based on EIA RS-485
Communication method : Half-duplex start stop synchronous
Data transfer rate : 2400, 4800, 9600, 19200 bps (Selectable by key)
Parity : Even, Odd and No (Selectable by key)
Stop bit : 1 and 2 (Selectable by key)
Communication protocol : WIKA protocol, Modbus RTU, Modbus ASCII (Key selectable)
Number of units connectable : Maximum 31 units to 1 host computer
Communication error detection : Double detection by parity and checksum
Digital external setting
: The SV from the programmable controller (with the option SVTC) can
be digitally transmitted to the CS4S (with the option [CR5]).
(The Setting value lock of the CS4S must be set to Lock 3)
When the data from the programmable controller exceeds the
SV high limit or low limit value, the CS4S ignores the value, and
performs the control with the former value.
The control desired value adds SVTC bias value to the value
received by the SVTC command.
SV1/SV2 external selection [option code: SV2]
SV1 or SV2 can be selected by the external contact.
When this option is added, the option [CR5] cannot be added with it.
Contact open between 13-14
: SV1
Contact closed between 13-14 : SV2
Contact current
: 6 mA
Terminal cover [option code: KAB]
Electrical shock protecting terminal cover
