• High Speed Thrust Bearing proximity sensing
– Proximity probe input at Microboard J8-15 or
Limit Switch input at I/O Board TB3-81.
• Flow Sensor – Paddle type or Factory Mounted
Thermal Type. The paddle type applies 115 VAC
to the I/O Board Digital inputs TB4-12 (evapora-
tor) and TB4-11 (condenser). The factory mount-
ed thermal type (available with style F chillers),
applies +5 VDC to the microboard Analog In-
puts at J7-14 (evaporator) and J7-16 (condenser).
Flash memory card version C.MLM.01.07.xxx
and C.MLM.01.07A.xxx automatically selects the
Flow Sensor input, either Analog or Digital per
the Chiller Style/Compressor setpoint selection.
Flash memory card version C.MLM.01.08.xxx
(and later), allows the use of either the Thermal
type(Analog)orPaddle-type(Digital)owsen-
sors in the style F chillers. With these versions, the
actual Flow Sensor type present must be entered
using the Flow Switch setpoint.
• Oil Heater Outputs – Either TB1-34 or TB1-64 on
I/O Board.
• Refrigerant Level Control Default Period – Either
3.5 seconds or 10.0 seconds.
• “Oil – Variable Speed Pump-Pressure setpoint
Not Achieved” safety shutdown threshold – Ei-
ther 25 psid or 35 psid.
Flash memory card version C.MLM.01.07.xxx and
later are applicable and backward compatible to all YK
chiller style/compressor combinations. They contain
all control variables for all combinations. For correct
chiller control, the correct CHILLER STYLE/COM-
PRESSOR combination must be entered. Once the ap-
plicable Chiller/Compressor combination is entered,
the program automatically bundles the functionality
and chiller control per the tables below.
For example, if equipped with C.MLM.01.08.105A
(or later):
Example 1
If the chiller is a style F and equipped with a J or H3
compressor, enter “Style F/J,H3 Compr”. The program
will read the Proximity probe input at Microboard
J8-15, control the Oil Heater from TB1-64, make the
Level Control Period Default 3.5 seconds, the Oil Pres-
sure safety threshold below is 35 psid and will read
the Flow Sensor inputs at either I/O Board TB4-11/12
or Microboard J7-14/16 as programmed with the Flow
Switch setpoint.
Example 2
If the chiller is a style E and equipped with a P com-
pressor, enter “Style E/P Compr”. The program then
reads the Proximity Limit Switch at I/O Board TB3-81,
controls the Oil Heater from TB1-64, makes the Level
Control Period Default 10.0 seconds, the Oil Pressure
safety threshold below would be 25 psid and reads the
Flow Sensor input at I/O Board TB4-11/12.
