Warning Read and follow the safety precautions and general instructions in this manual and
also in the SKF manual "Safety and general instructions for lubrication systems." Failure to follow these
instructions could result in serious injury or damage to the lubrication system or the equipment that is
lubricated.
2 General description
SKF ST-1100s is a control center for a chain lubrication system. The system lubricates each link of the chain either
according to the settings in the automatic mode or manually. Lubrication interval can be set either on the basis of time
or number of chain rotations. The lubrication pulses are timed by means of an inductive sensor, which recognizes the
links of the chain.
3 Design
The main switch of the SKF ST-1100s control center is located at the bottom edge of the center enclosure. The
enclosure cover has a green indicator lamp for power and a red indicator lamp for alarm. The control panel of the
center is located inside the enclosure.

3.2.4 Display
The control panel has a 6-character 7-segment display.
The display has been divided into two groups:
•2-character value display indicates the code for phase or value
•4-character time display indicates the value corresponding to the code
When the display shows a time value, the decimal point blinks at intervals of one (1) second.
The time is displayed as hours and minutes. For example, 12.34 indicates 12 h 34 min and 123.4 indicates 123 h 40
min.
When the control center is in normal or alarm mode, the code corresponding to the program phase is shown on the
value display.
Phase code Phase description Time display
Ct Interval, time counted Interval duration
Cr Interval, rotations counted Full chain rotations
Ht Manual operation, time displayed Interval duration
Hr Manual operation, number of rotations displayed Full chain rotations
P Lubrication Number of lubricated links

pressed.
Display code Description

In this application the setting must be SPr.
PASS Entering password.
The password is displayed on time display.
The program returns to display program phase code (normal or alarm mode) in the following cases:
−Setting- or arrow button was last pressed more than three (3) minutes ago
−both arrow buttons are simultaneously pressed down for 3 seconds
−-button is used to browse the phase code on the display
−the center is restarted
4 Operation
4.1 Lubrication modes
Select the lubrication mode with the setting code L.d.
4.1.1 Automatic lubrication (1)
The lubrication interval is set as hours (0 ... 9999 h). The display code is Ct during the lubrication interval and the
elapsed interval time is displayed. Lubrication starts when the set interval time has elapsed. After the lubrication, the
system starts counting the interval again. Lubrication can also be started manually by pressing the Setting-button.
The interval counting can be interrupted by closing the interlocking input. If the configuration parameter Timeout is
not set at 0, interval counting is stopped also if no chain pulses have been received during the set time value.
If the interval counting has been stopped, the code displayed is Linstead of Ct.

110s2AEN.doc 16.01.2013 Rev. 2A 6 (12)
4.1.2 Automatic lubrication (2)
The lubrication interval is set as full chain rotations (0 ... 9999 r). The display code is Cr during the lubrication interval.
Lubrication starts when the set amount of full chain rotations has been reached. After the lubrication, the rotation
count is reset to 0. Lubrication can also be started manually by pressing the Setting-button.
4.1.3 Manual lubrication (1)
The code displayed is Ht. The display shows elapsed time as hours since the previous lubrication. Lubrication is started
by pressing the Setting-button.
4.1.4 Manual lubrication (2)
The code displayed is Hr. The display shows the number of chain rotations since the previous lubrication. Lubrication is
started by pressing the Setting-button.
4.2 Lubrication
Lubrication is performed the same way in all lubrication modes described above. Each link pin of the chain is lubricated
once during a lubrication phase. The number of link pins per rotation can be set by means of parameter Link pins per
rotation.
The setting code is L.P.
Usually each link pin is lubricated one after another. If the parameter Divider (display code P.F.) is set to value > 1, a
lubrication pulse is sent when the chain pulse counter reaches the divider value. Lubrication pulses are sent according
to the parameter Link pins per rotation . For example, if the Divider = 3, a lubrication pulse is sent at every third chain
pulse and lubrication takes three (3) full chain rotations.
During lubrication phase, code Pis displayed as well as the number of lubricated link pins. The lubrication phase stops,
when the number of the lubricated link pins reaches the set value. Lubrication can be stopped by pressing the Setting-
button.
When lubrication stops, the reading of the lubrication counter is added by one unit. The counter reading does not
increase if the lubrication has been stopped prematurely.
In addition, there are two other parameters for controlling the lubrication pulse:
•Pulse length (display code P.L.) which is used to adjust the duration of the lubrication pulse
•Pulse delay (display code P.d.) which is used to adjust the delay time between the chain pulse and the lubrication
pulse
See also section 5.3.6 Configuration settings
.

110s2AEN.doc 16.01.2013 Rev. 2A 7 (12)
4.3 Alarms
The control center goes into alarm mode if the low level switch of the lubricant reservoir closes during lubrication.
Code AL is displayed as well as alarm duration in hours and minutes.
If the parameter P.r. has been set in status Yes, the pressure of the pump is monitored with an external pressure
switch. The control center goes into alarm mode if the switch is closed when the lubrication pulse starts or if the switch
is open when the lubrication pulse ends. Code AP is displayed as well as alarm duration in hours and minutes.
The Alarm indicator lamp on the cover is lit and the alarm relay goes into alarm mode.
The alarm can be reset with the Setting–button. An interrupted lubrication phase can be restarted manually by
pressing the Setting-button.
4.4 Air blowing
The purpose of air blowing is to clean the lubrication point before pumping the lubricant.
Air blowing starts in the beginning of the lubrication phase five (5) sensor pulses before the pump starts.
The sensor pulse starts air blowing during lubrication. The duration of the air blowing is set as seconds with parameter
A.b. If the value is set to 0, air blowing is not in operation.
4.5 Power failure
All settings are stored in the memory which is protected against power failures (EEPROM). If a power failure occurs,
the current status of the control center is stored in the memory: interval, alarm or lubrication. Once the power is back
on, the operation will resume from the status it was in before power failure occurred. An exception to this is the
lubrication phase. After the power failure, operation starts with interval counting.
5 Settings
5.1 General
Center settings can be divided into two groups:
•Set values
•Configuration settings
Set values are lubrication system basic values. For example, lubrication interval set values can be changed in settings
mode.
Configuration settings determine the center functions according to the lubrication system. These settings are usually
factory settings and there should not be any reason to change them during operation.
All settings are password-protected.

110s2AEN.doc 16.01.2013 Rev. 2A 10 (12)
Note! Configuration settings can be accessed with password 22.
Note! There are several other settings in the configuration mode, but they are not documented in this
manual as the operator is not allowed to change them.
