The remote temperature sensor on the rear of the immersion circulator re-
quires a 4-pin connector that must mate to a LEMO # ECP.1S.304.CLL. The
Sensor
immersion circulator uses a 3 wire sensor, but a 4 wire sensor can be used
(pins 3 and 4 are interconnected in the control head). The pin-out is:
2 1
Pin 1 and 2 = Pt100 +
3 4
See Section 4 for instructions to enable the remote sensor.
The Multifunction port on the rear of the immersion circulator is used in
conjunction with an optional accessory box to select and activate additional
features. See Section 4 for additional information.
If your computer does not automatically recognize the USB driver, installa-
tion instructions are provided in the Appendix.
Tubing
Ensure none of the tubing comes in contact with the power cord.
Tubing is normally used to connect the pump to an external application.
NOTE For maximum pressure to the external application cap the pump
nozzle with the supplied fitting, it may be necessary to remove the immersion
circulator from the bath to access the nozzle.
NOTE The maximum allowable length of tube depends largely on the
size, form and material of the external vessel. The length of tube and its
diameter, combined with the circulating capacity, have a large effect on the
temperature stability. Whenever possible, use a wider tube diameter and place
the application as close as possible to the circulator.
Extreme operating temperatures will lead to extreme temperatures on
the tube surface, this is even more critical with metal nozzles.
• the required tube material depends on the heat transfer liquid used
• tubes must not be folded or bent
• after prolonged use, tubes may become brittle or they may get very soft,
check them on a regular basis and replace if necessary
• secure all tube connections using clamps
When using the internal bath only, the plumbing connections can be closed
with the supplied plate and union nuts.
