CONTROLS INTERFACE
MAIN SCREEN
The Main screen is the "dashboard" of the chiller. High level status information is presented so that a user can quickly
understand the operating status of the chiller. Controller use and navigation is discussed in depth in the CONTROLLER
AND NAVIGATION section.
The Main screen is the default screen.
Additional Screens are accessible through the navigation buttons below the screen.
The current fluid temperature is indicated in the middle of the main screen. Bottom left is the chiller status indicator.
SAFETIES
Safeties include: Flow Switch, Breaker, High Head Pressure, Oil Pressure, and an ECM (Electronic Control Module).
UNIT START-UP PROCEDURES
POWER UP
When power is applied to the chiller, the HMI will boot up to the main screen. The chiller will start if both the control
power switch, and the chiller start/stop switch are in the on position. This insures automatic restart in the event of a
power outage. As with the chiller, the process pump will only start if the output power switch, and the process
pump start/stop switch are both in the on position.
CAUTION: EQUIPMENT DAMAGE!
Ensure that the oil sump heaters have been operating for a minimum of 24 hours before starting. Failure to do so
may result in equipment damage. Check oil level before starting.
CAUTION: COMPRESSOR DAMAGE!
Catastrophic damage to the compressor will occur if the isolation valves are left closed on unit start-up.
START UP
Refer to the "9 Easy Steps" document for the most current chiller start-up procedures.
