The ACT 250 controller
Dear Customer,
You have just bought an
ACT 250 controller. In
order to ensure the best
possible performance of the
equipment and your
complete satisfaction in
using it, we advise you to
read this addendum
carefully before attempting
to service or use your
controller.
Insertable “box”version
Part No. 108320
Integrable “OEM”version
Part No. 108151
ACT 250 controller
Main characteristics
This controller drives ATP 150 or ATP 400 pumps,
providing their power supply and enabling remote control.
The ACT 250 controller is available as:
■an insertable “box”version with case,
■an integrable “OEM”version without case.
This version can replace the “box”version when
integrating the pump in a complex installation or device.
■Dry contact signal outputs
■Opto-isolated control inputs
■RS 232 / 485 serial links
■Operate at all voltages from 85 to 265 V, 50/60 Hz
The ACT 250 controller is a new product, not described in Edition 09 of the ATP Series
Pump User Manual.
This addendum provides the additional information needed to use the controller.

#adrADRaaa<CR>[<LF>]
adr = address of device before this command
aaa = new address of device
condition : 000 ≤aaa ≤255

each device.

Enables or disables checksums on reply strings

reply string
or
#adrCKSOFF<CR>[<LF>]
Disables the ASCII checksum character at the end of a
reply string
#adr,ok,Sfor CKSON
#adr,ok for CKSOFF
This feature enables the user to test whether a transmission error has
occurred for the reply string.
Sis a character whose ASCII value is the 7-bit checksum of all ASCII
character values from the start of the reply string to the character
preceding the S. The 8th bit of S(most significant bit) is always 1.
Starts the specified running-in cycle
#adrCYC1<CR>[<LF>] to start running-in program 1,
or
#adrCYC2<CR>[<LF>] to start running-in program 2
#adr,ok
Running-in program 1 should be executed after a pump maintenance
operation (change of bearings).
At the end of the program, the pump maintenance parameters are
updated and the “maintenance requested”alert can be cleared.
Program 2 is used after regreasing (ATP series only), or after
prolonged storage (ATH 20/40 only).

ttttt : pump operating time (hours)
uuuu.o: (reserved)
www : pwm (reserved)

The main characteristics of the pump and its controller are sent over
the RS link, at the rate defined by the DLI command.
Note: any new characters arriving on the serial port (RS 232) will
cancel the automatic DataLogger transmission.
