1 Safety instructions
The filter controls RM-310 C / RM-310 CT or RM-310 C Plug and Play / RM-310 CT Plug and
Play carry hazardous electrical voltage when connected to the mains.
Improper installation of
the connected electrical equipment may cause device failure, serious or even fatal injuries. In
addition to general safety rules for equipment in in
dustrial electrical installations, pay particular
attention to the following points:
The equipment must only be installed by qualified persons according to the provisions of the
standards IEC 364 and DIN VDE 0105 for electrical equipment.
All applicable la
ws, conditions, rules and regulations governing the installation of electrical
equipment must be observed.
Equipment with protection rating IP00 without covers must only be configured by authorised ex-
pert staff when disconnected and whilst observing the lo
cal safety and accident prevention
rules.
The filter controls RM-310 C / RM-310 CT or RM-310 C Plug and Play / RM-310 CT
Plug and
Play must only be operated within the permitted application range.
Switch off the supply voltage before replacing the filter controller
s or components connected to
them. Failure to do so may cause equipment damage.

2 Device descriptions
RM-310 C / RM-310 CT
The RM-310 C / RM-310 CT controller is the master control of the modular filter control system for filtering
separators with compressed air pulse cleaning. The front of the device with text display, membrane key-
pad and status LEDs is used to display operating and alarm messages and to set parameters. The intelli-
gent I/O modules handle decentral measuring and control tasks. The R-IMC-Bus (RECO – Inter Module
Communication) employed for data transfer between the individual control components was developed
specifically for use in industrial environments. Once the supply voltage and the intelligent I/O modules
have been connected the RM-310 C / RM-310 CT filter control works fully automated without further han-
dling.
The following diagram shows the general layout of an R-IMC bus controller environment with the controller
RM-310 C / RM-310 CT and the I/O modules RM-V 8 and RM-V 16 provided for this controller type for use
as a pulse filter.

RM-310 C Plug and Play / RM-310 CT Plug and Play
The controller types RM-310 C Plug and Play / RM-310 CT Plug and Play differ from the types
RM-310 C / RM-310 CT in that the prefabricated cables from RECO are used to connect the I/O modules.
This means that the time required for electrical installation is considerably less. The RM-V 6 I/O modules
intended for this plug-and-play system are available with 6 (RM-V 6/6), 5 (RM-V 6/5), 4 (RM-V 6/4) or 3
(RM-V 6/3) valves.
Since the controller types RM-310 C / RM-310 CT and RM-310 C Plug and Play / RM-310 CT
Plug and Play do not otherwise differ, for the sake of simplicity only the types RM-310 C /
RM-310 CT are mentioned in the further descriptions of this manual. The complete type desig-
nations only appear where there are differences.

5 Setting procedure
5.1 Function in "as delivered" condition
The following parameters must be set before operating the RM-310 C / RM-310 CT:
E0 Cleaning control functions
EA Number of valves
EB Number of I/O modules
The RM-310 C / RM-310 CT operates automatically once the cleaning control functions, number of valves
and number of I/O modules have been set.
Cleaning starts when the filter’s differential pressure Δp has reached the "DP-Start" value (factory set-
ting: 1200 Pa). The solenoid valves are controlled sequentially. By cleaning the differential pressure drops
after a certain period of time. Once the differential pressure has reached the value “DP-Start” minus
“DP-Hyster.” (factory setting: 300 Pa), i.e. the differential pressure is 1200 Pa - 300 Pa = 900 Pa, clean-
ing stops.
If a different function is desired or additional functions shall be activated, the parameter setting of the
RM-310 C / RM-310 CT must be changed. See sections 5.3 "Parameter selection level" to 5.9 "Parameter
list" on this.

5.3 Parameter selection level
To view the parameters and their values the user must switch from the operating level to the parameter
selection level. The and keys must be pressed simultaneously until the green “ON“ LED goes off
(approx. 3 seconds).
All parameters with their set values can now be viewed in sequence by repeatedly pressing the or 
key. Inactive or hidden parameters are automatically skipped (see section "Activated and deactivated pa-
rameters / faded in and faded out parameters" on this page).
Parameter blocks
To ensure an uncluttered view of the device’s parametrisation parameters referring to the same function
are grouped into blocks (C0, D0, E0, etc.). For example, the block D0 “Δp-controls” includes all parame-
ters (D1, D2, D3, etc.) referring to the differential pressure-dependent cleaning control (short: Δp-
controls).
Activated and deactivated parameters / faded in and faded out parameters
Two different types of parameter blocks are available: those that can be activated and deactivated and
those that can be faded in and faded out. A deactivated block is inactive. All parameters assigned to it are
without function and are not shown. With faded out parameter blocks the associated parameters are ac-
tive, that is, functioning. They are just not shown.
To activate a disabled parameter group or to fade in a faded out parameter group switching to
the parameter setting level is required (see section 5.4 "Parameter setting level" on page 17 on
this).

5.4 Parameter setting level
To change the value of a selected parameter or to activate and deactivate or fade in or fade out a parame-
ter block the user must switch from the parameter selection level to the parameter setting level. To do so,
the ENTER key must be pressed until the text display switches over (for parameters locked by a code) or
the green LED "ON" begins to flash (with unblocked or previously unblocked parameters).
For parameters blocked by a code, the entry of a 4-digit code is required to release the parame-
ter (refer to section 5.5 "Code input to clear locked parameters" on this).
Subsequently, the parameter value can be changed or the parameter block activated or deactivated or
faded in and faded out by pressing the or key.
To save the set value or the status of the parameter block (activated / deactivated or faded in / faded out)
and return to the parameter selection level the ENTER key must be pressed until the green LED “ON”
goes out (approx. 1 second).
5.5 Code input to clear locked parameters
There are 3 different codes that are used to allow access to certain parameters to authorised persons on-
ly. In the parameter selection mode, the row 4 of the display shows what code has to be entered to re-
lease the displayed parameter (parameter code 3, 4 or 5). If nothing is displayed in the row 4, the relevant
parameter can be accessed without code. The required codes can be found in section 5.9 "Parameter list"
on page 23.
The 4-digit code must be entered as follows:
1. The code digit is selected by briefly pressing the ENTER key.
2. The digit value is set by briefly pressing the or key.
3. The set code is confirmed by prolonged pressing of the ENTER key.
If the code entered is wrong the message “!Invalid input!” appears for 2 seconds. The code input
must be repeated.
If the code entered is correct the message “!!!! OK !!!!” appears for 2 seconds.
All parameters that were blocked by the same code are now released for setting. The parameters are
blocked again if no key of the device is pressed for 20 minutes.
5.6 Return to the operating level
To get to the operating level the and keys must be pressed simultaneously until the green LED lights
(approx. 3 seconds).
