1 Safety instructions
The filter control system RM-208 CB when connected to the mains poses an electrical hazard.
Device failure, serious or even fatal injuries may occur as a result of improper installation of the
connected equipment. Consequently, follow in particular the points set out below in addition to
the general safety regulations for equipment in industrial electrical installations
:

Installation of the device may be carried out only by qualified experts, in accor
dance with the
provisions of IEC 364, DIN VDE 0105 for electrical equipment.

All applicable laws, conditions, orders and regulations governing the setting up of electrical
equipment must be observed with respect to the installation site.

Setting of equipme
nt with degree of protection IP00 without covers, may only be performed by
authorized expert staff, when disconnected, and whilst observing the local safety and accident
prevention regulations.

The RM-208 CB may only be operated in the permitted operating area.

Switch off the mains supply before replacing the filter control or any components connected to
it. Otherwise the equipment may be damaged.
2 Equipment specification
The RM-208 CB is used to control 24 V DC solenoid valves on filtering separators with compressed air
pulse cleaning. After connecting the supply voltage, the filter control system functions fully automatically
without further activation.

Other connections

A device (switch, power circuit breaker) must be located in the proximity of the filter controller
RM-208 CB
, which enables the disconnection of all poles of the device from the mains
voltage / supply voltage. The device (switch, power circuit breaker) has to be easy accessible
for the user and to be marked as disconnecting device for the equipment.
The wires and cables used for the connection of the controls must be suitable for an ambient
temperature of up to 130 °C.
Use shielded cable for all bus lines! The shiel
ding must be connected unilaterally to the
protective earthing (PE).
Signal cables must not be laid parallel to power cables.

Tighten all cable glands in use so the cables are properly enclosed and water cannot
penetrate.
Cable glands that are not in use must be closed or replaced by blind plugs.

5 “Step by step” settings
5.1 Function when shipped
The down time cleaning input 10, 11 is bridged at the factory. Once the supply voltage is at RM-208 CB,
the solenoid valves are controlled consecutively in sequence. The filter control system automatically
detects how many valves are connected.
For connecting an external ∆p switch, see section 6.3 “Cleaning via start / stop input (external ∆p switch)”.
To activate the down time cleaning, see section 6.2 “Down time cleaning”.
If another function is required or if additional functions are to be activated, the parameter setting of the
RM-208 CB must be changed. See also section 5.2.
5.2 Setting parameters
To set or check the parameters, proceed as follows:

Use the parameter list in section 5.3 to search for the parameters you want to change or check.
On the RM-208 CB, press buttons and 
simultaneously, for at least 3 seconds. The
program then changes from operation mode to parameter selection mode. The parameter P01
“Pulse time” is displayed on the text display at its set value.

Press the button to call up all following parameters P02 ... P11 in sequence. The parameters
already displayed can be accessed by repeatedly pressing the button.

To change the value of a displayed parameter, press the ENTER button for at least one
second. The program then changes from parameter selection mode to parameter setting mode.

Press the

button to increase the parameter value displayed in increments. Press the

button to decrease the parameter value displayed.

Press the ENTER button for at least 3 seconds. The new parameter value is stored. The text
display will briefly display the message “Store
”. The program automatically returns to the
parameter selection mode. You can now call up other parameters and check or change their
values.

So that the program changes from parameter selection mode to operation mode, press buttons
and simultaneously for at least 3 seconds.
If the program is still in parameter setting mode, follow the instructions given under point .
The symbols shown on the right will be shown in the
lower left-
hand corner of the text display. They
indicate to the operator which mode the equipment is
currently in.
+ -Operation mode
+^-Parameter selection mode
+>-Parameter setting mode
If no buttons are pressed for 4 minutes, the RM-208 CB automatically returns from parameter
selection mode or parameter setting mode to operation mode with the last values stored.

*Number of all valves connected to the RM-208 CB and to the expansion modules. The parameter is used by the equipment for
internal monitoring purposes and need only be set, if expansion modules are fitted. If the equipment detects that the total
number of valves set is different from the actual number of valves controlled, an alarm message is issued.
** If the parameter is set to the value 0 h, the alarm is switched off.
The parameters P09 and P10 are only displayed if the service operating hours code (parameter
P11) has been entered.

6 Operating modes
6.1 Test mode
In test mode, the most important functions in the control sequence are checked and shown on the text
display. To start test mode, call up parameter no. P08 “Test mode” (see section 5.2 for more information)
and select one of the following test modes:
Test mode 1 (Valve test)
Each valve connected is activated in sequence and shown in the text display.
Test mode 2 (Input test)
The signal statuses of the inputs are displayed on the text display.
Test modes 3-5
For manufacturer purposes only
Test mode 0 (test mode off)
Test mode is switched off.
6.2 Down time cleaning
To activate down time cleaning, perform the following steps:
Remove the factory-fitted wire jumper on input 10, 11.
Connect a free auxiliary contact (make contact) of the fan contactor to terminals 10 and 11. The input
should be operated in isolation.
Set parameter P05 “Down time cleaning cycles” to the required number of cycles (see also section 5.2
“Setting parameters”).
If the fan is switched on, the contact on 10, 11 closes and switches on the cleaning. When switching off
the fan, the contact on 10, 11 opens and activates the down time cleaning. The down time cleaning cycles
set are carried out. The RM-208 CB then shuts down.
6.3 Cleaning via start / stop input (external ∆p switch)
If the cleaning is controlled via an external ∆p switch, the isolated contact on the ∆p switch must be
connected to the start / stop input 12, 13.
During down-time cleaning, the start / stop input 12, 13 is inactive.

9 Details on the equipment function
Cleaning
Cleaning starts at the first valve. If the cleaning is interrupted via the start/stop input 12, 13, the control
sequence is continued at the next cleaning procedure. The cleaning then starts at the valve following the
last valve activated.
If the control is reactivated following a mains voltage failure, a restart is carried out.
Relay output 8, 9 to control extractor elements
If automatic components for dust removal (extractor elements) are fitted, these need to be in operation
during cleaning and during down time cleaning. Connect the cut-out for controlling these drive units to the
isolated output 8, 9.
“Alarm” relay output 5, 6, 7
As soon as the supply voltage is present on the RM-208 CB, relay contact 5, 6 closes and contact 6, 7
opens. In the following situations, relay contact 5, 6 opens and contact 6, 7 closes:
Supply voltage failure
Failure of a voltage internal to the equipment
Fault in a connected O module
Total number of valves is set incorrectly (parameter P04)
