3. Setup

Setup should occur before using this controller, to set the Control action and Alarm type according to the users’
conditions, using the DIP switch (SW302) and Rotary switch (SW301).
Default values: PD control, No alarm action
If the users’ specification is the same as the default value of the RC-600, it is not necessary to set up the controller.
3.1 Taking the internal assembly out
Before the power supply to this instrument is turned on, take the internal assembly out from the case in the
direction indicated by the arrow by holding the latches (top and bottom of the instrument).
3.2 Switches setting
A control action can be selected with the DIP switch (SW302).
When Alarm types other than No alarm action are ordered, Rotary switch (SW301) will be equipped, and alarm
action can be selected.
Using a small flat blade screwdriver and tweezers, set the following with the DIP and Rotary switches.

3.3 Inserting the inner assembly into the case.
By holding the latches (top and bottom of the instrument), insert the inner assembly into the case.

4. Mounting to the control panel
4.1 Site selection

CautionUse within the following temperature and humidity ranges.
Temperature: 0 to 50 (32 to 122 ) (No icing), Humidity: 35 to 85%RH (Non-condensing)If the RC-600 is installed within a control panel, the ambient temperature of the unit must be kept to under
50 . Otherwise the life of electronic parts (especially electrolytic capacitors) of the unit will be shortened.
This instrument is intended to be used under the following environmental conditions (IEC61010-1):
Overvoltage category , Pollution degree 2
Ensure the mounting location corresponds to the following conditions:• A minimum of dust, and an absence of corrosive gases• No flammable, explosive gases• No mechanical vibrations or shocks• No exposure to direct sunlight, an ambient temperature of 0 to 50 (32 to 122 ) that does not change rapidly• An ambient non-condensing humidity of 35 to 85%RH• No large capacity electromagnetic switches or cables through which large current is flowing• No water, oil or chemicals or where the vapors of these substances can come into direct contact with the unit3

4.4 Mounting and removal

CautionAs the case is made of resin, do not use excessive force while screwing in the mounting bracket,
or the case could be damaged.
The torque should be 0.12N•m.
Mounting
Mount the controller vertically to a flat, rigid
panel.
Mountable panel thickness: 1 to 15mm(1) Insert the unit from the front of the panel.
(Fig. 4.4-1)(2) Attach the mounting brackets to the slots
at the top and bottom of the case, andsecure the controller in place with thescrews provided. (Fig. 4.4-2)(Fig. 4.4-1)
Removal(1) Turn the power to the unit OFF, and disconnect all wires.
(2) Unfasten screws of the mounting brackets, and remove the brackets.
(3) Pull the unit out from the front of the panel.
(Fig. 4.4-2)

5. Wiring
Warning

Turn the power supply to the instrument off before wiring or checking.
Working or touching the terminal with the power switched on may result in severe injury or death
due to Electric Shock.。

Caution• The terminal block of this instrument is designed to be wired from the left side. The lead wire must be
inserted from the left side of the terminal, and fastened by the terminal screw. The torque should be 0.63N•m.
• Use a thermocouple and compensating lead wire according to the sensor input specifications of this controller.
• This instrument does not have a built-in power switch, circuit breaker or fuse.
It is necessary to install them near the controller.
(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)• When using a relay contact output type, externally use a relay according to the capacity of the load to protect
the built-in relay contact.
• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC sources or load wires.
• Do not apply a commercial power source to the sensor which is connected to the input terminal nor allow thepower source to come into contact with the sensor.

(Fig. 5.3-1)

6.1 Starting operation
After the unit is mounted to the control panel and wiring is completed, operate the unit following theprocedures below.
(1) Switch power supply to the RC-600 ON.
For approx. 3sec after power-on, sensor input character and temperature unit [K:,, J:,] are indicated on the SV display. During this time, all outputs and LED indicators are in OFF status.
After that, SV is indicated on the SV display.
(2) Input each set value.
1 SV setting
Set the SV using the [+100], [+10], [+1], [-100], [-10] and [-1] Keys.
2 Alarm value setting(Table 6.1-1)
Set alarm values.
Alarm type
Setting range
The alarm action point is set by deviation from the SVHigh limit alarm-199 to input span ( )(except Process alarm). When the PV goes outside theHigh limit alarm with
-199 to input span ( )range, the alarm output turns ON.
By pressing the ALARM Key for 3 sec, the unit enters the standby

(3) Turn the load circuit power ON. Control action starts so as to keep the control target at the SV.
56.2 Performing Auto-reset (offset correction)
Auto-reset is performed
Auto-reset can be performed in PD control.
Temperature
It cannot be performed in ON/OFF control.
SV
Offset span
When PV is stabilized (stable indication of the PV)
within the proportional band, press the RESET Key
for 3 sec. Auto-reset will be performed, and offset
will be automatically corrected.
Offset is corrected
While auto-reset is performing, one bar of the LED
deviation indicator flashes depending on deviationTime
between SV and PV.
Since the corrected value is internally memorized,(Fig. 6.2-1)
it is not necessary to perform the auto-reset again as long as the process is the same.
Auto-reset is finished in approximately 4 minutes. It cannot be released while performing this function.
