(Flash Memory Card version C.MLM.01.08.xxx and
later)
Style F chillers (and later) are provided with factory
mounted thermal-type fl ow sensors for the evapora-
tor and condenser. Flash Memory Card version
C.MLM.01.08.xxx and later allow these chillers to use
either the thermal-type or fi eld installed paddle-type
fl ow sensor. The thermal-type sensors interface to
Microboard +5Vdc analog inputs at J7-14 (evaporator)
and J7-16 (condenser). The paddle-type sensors inter-
face to the I/O board 115Vac digital inputs at TB4-12
(evaporator) and TB4-11 (condenser). In order for the
program to read the appropriate inputs for the fl ow sen-
sor status, the actual sensor type used must be entered
at the keypad OPERATIONS Screen using Service
Access Level.

If the chiller style in the Chiller Style/Compressor
setpoint on the OPERATIONS Screen is set to "F" (any
compressor), the "FLOW SWITCH" key appears on the
OPERATIONS Screen allowing the fl ow sensor type to
be entered. The selections are "Analog" (thermal-type)
or "Digital" (paddle-type). If Analog is selected, the
program reads the thermal-type fl ow sensor inputs at
Microboard analog inputs J7-14 (evaporator) and J7-16
(condenser) and ignores the Digital inputs. If Digital is
selected, the program reads the paddle-type sensor inputs
at the I/O Board digital inputs TB4-12 (evaporator) and
TB4-11 (condenser) and ignores the Analog inputs.
Enter the applicable fl ow sensor type as follows:
1. Select SETPOINTS/SETUP/OPERATIONS
Screen.
2. Press FLOW SWITCH key.
3. Use
or
keys to select fl ow sensor type. Each
time the key is pressed, Analog or Digital is alter-
nately displayed.
4. Press ENTER (✔) key.
