14.3.3 Automation Cable: Dual Pumps Control Cable
Part #: CBL-DUAL
Using two NE-9000 peristaltic pumps, this cable creates a dual pumping system, with both pumps
operating in the same direction.
This cable is attached to two NE-9000 peristaltic pumps via their RS-232 connectors. In this setup, with
the pumps configured for this operation, one pump acts as the Master controller. The pumps can be set to
Dual Pump Mode, whereby the second pump will always follow the program on the first pump, including
starting, stopping, direction changes, and rate changes.
When either pump stops, for any reason, the other pump will stop.
14.3.4 Valve Controller
Part# ADPT-VALVE-INTERFACE-1 (For one pump)
Part# ADPT-VALVE-INTERFACE-2 (For two pumps, includes CBL-TTL-1)
Provides a control interface for your electronic valves. Attach your electronic valves, and the interface
will control the activation of the valves. The 2 pump interface is used to create a continuous
dispense/refill system.
14.3.5 Foot Switch
Part #: ADPT-2
Allows the pump to be operated from a foot switch. Attaches to the TTL I/O connector.
14.3.6 Lockout Disable Key
Part#: ADPT-LOCKOUT-KEY
Enables setting Keypad Lockout mode and allows changing of settings while Keypad Lockout is set.
14.3.7 Firmware Upgrade
Part#: CPU-NE9000, Upgraded firmware.
Contact your dealer for this upgrade and to determine the current available version of the pumps internal
firmware.
14.4 Troubleshooting and Maintenance
Maintenance: Periodically, a new tube should be used or a new section of peristaltic tubing should be
used. Add grease to the Cassette shaft and the surface of new tubing.
Pump head may need to be replaced once a year depending on usage.
The mechanism should be kept clean to prevent wear and tear.
RS-232 Communications: If no RS-232 communications is possible or garbled responses are received
from the pump, check the following:
If the triangle appears in the upper left of the LCD display, then the pump is receiving valid
communications. The communications problem is probably with the receiving communication application
or with the receive line on the cable.
If the Basic communications mode is used, check if the pump is in Safe communications mode. See
section 12.2, RS-232 Protocol:, for instructions on how to change the communications mode.
Verify the pump’s baud rate and network address. To set the RS-232 communications parameters, see
section 6.14, ‘Setup’ .
Using a lower baud rate may also improve the reliability of the RS-232 communications.
