Operation Overview
The MCH operating software serves two basic functions. First, it provides an intuitive, feature-
rich touchscreen control interface, giving the operator quick access to temperature settings, pump
speed control, system test and status information, and customization features. Second, it
constantly monitors the MCH's internal systems to ensure that the hardware is functioning
properly. An alarm will sound within seconds of any operational problem, alerting the operator to
the issue.
The operator controls the MCH using an LCD touchscreen display, using four basic modes. In
TESTING mode (which is run automatically when the system is powered on), the MCH tests all
internal relays and displays the results to the operator in a simple pass/fail format. In STANDBY
mode, the system is idle, awaiting operator input. In PRIMING mode, the MCH operates the
pump and valve to remove air from the tubing lines. In RUN mode, the device circulates the
water through the cold water tank and the heater chamber as necessary to maintain the
circulating water at the operator-selected temperature.
The MCH is designed with EMI protection to operate effectively with minimal interference from
other nearby equipment. It is shielded so that electronic noise generated within its enclosure will
not affect operation of other equipment in use in the same area as the MCH.
Add Ice!
The MCH uses ice-based cooling and has a valved, insulated cold water tank that is able to retain
cold water for a considerable length of time. For procedures that do not require extensive
cooling, the MCH will operate safely and effectively with room-temperature water in the tank;
however, the temperature control algorithms are optimized for the use of ice water. The MCH
will operate more efficiently with cold water (0-10˚C) in the tank.
