*) The interlocking inputs can be equipped with 115VAC/10mA or 230VAC/5mA relays when using the CB-105 board.
**) In progressive lubrication mode (ProFlex) the input is specified for spray air pressure switch use AS1 (XA: 1, 11) and spray
air pressure switch use AS2 (XB: 21, 31)
***) In progressive lubrication mode (ProFlex) the input is specified for progressive distributor piston detector / pulse sensor
(CH1 XA: 9,19) and (CH2 XB: 29,39)
Pressure transmitter/switch inputs
There is a four (4) pressure transmitter/switch inputs reserved for two lubrication channels to control the lubrication system.
Depending of the operation mode and the lubrication systems to be controlled, the pressure transmitter/switch input accepts to
be connected to a pressure switch or pressure transmitter (
4&20mA / 0&250 bar) (2
-wire type). The operation mode is set
channel-specifically with the user interface.
Pump control outputs and low level inputs
The control centre has two pump control outputs (PC1, PC2) and low level switch inputs for the lubrication barrel (LL1, LL2) to
control the two pumps. The pump controlling method is selected through control centre configuration parameter (One pump for
both channels or both channels have separate pumps per channel and with or without dualset operation).
Shut-off valves
There is a separate shut-off valve control for both lubrication channels. The shut-off valve control is ON when the channel is
pressurized.
Spray air control and monitoring
The control centre has two air spray outputs (AC1, AC2) and two inputs for the grease spraying nozzle for air pressure
monitoring
3
air pressure switches (AS1, AS2). Lubrication channel specific air controlling for a channel is selected through
lubrication mode parameter and air pressure monitoring capability has separate parameter for a channel.
Alarm output
3
external signals
The alarm output is a potential-free change-over contact. Max load 230V / 1A
The centre is in alarm mode, when:
"
there are alarms from one or more channels
"
the centre is potential-free
The centre alarm is inactivated, when all the problems that triggered the alarms have been resolved and all alarms have been
reset at the control panel.
