Acess c

ontrol:

Depending  on  the  access  level,  the  user  is  allowed  to  take 
different  actions  on 

RCK-602 

plus

.  Three  different  access 

levels are available:
- Viewer: 

Standard mode, no need to enter a code. 

- Technician: 

Allows making changes to some system parameters by using 
the code: 123

- Administrator: 

Allows making changes to all system parameters (generally 
used when making the initial system configuration), using the 
code: 717

If 

RCK-602 

plus

 is configured to Technician or Administrator 

mode  and  the  device  remains  idle  for  15  minutes,  it  will 
automatically return to the Viewer mode.

Note: 

If an invalid code is entered, the controller returns to the 

Viewer access mode.

Inpu

ts and outputs: 

A summary of 

RCK-602 

plus

 inputs and outputs is 

displayed, indicating the value read from the sensor 
and the current state of the digital inputs and control 
outputs.

Mainten

ance: 

Displays  and  selects  compressors  or  fans  to  enter 
maintenance mode.
When in maintenance state, the equipment remains in 
the off state.

Hourmeters

:

Indicates the number of hours each compressor or fan 
has been running.

Dat

e

 

and

 

time

Sets the current date and time. This field is important 
for recording alarms and the logic that use the clock.

Indi

vidual pres

sos

tat:

Output associated to pressure control with individual 
(independent) setpoint and hysteresis.

Control status

:

Allows switching the system control on or off. When switched off,  

RCK-602 

plus

 only monitors the system but takes no action.

Note:

  Some  functions  such  as  downloading  presets  and 

changing some functions require the control to be off.

Alarm 

r

e

set

:

Resets the pressostat in manual or automatic reset condition. The 
reset will be recorded in the alarm history.

Economi

c setpoint:

Enables the economy setpoint for each group of pressostat.

Pump Down:

 

Activates the Pump Down function for each pressostat 
group.
