FLOW SWITCH
(Flash memory card version C.MLM.01.08.xxx and later)
Style E (and earlier) chillers are supplied with Paddle
type flow sensors. Style F (and later) chillers are sup-
plied with factory mounted Thermal type flow sensors.
The Paddle type sensors are connected to the I/O Board
115 VAC Digital inputs TB4-12 (evaporator) and TB4-
11 (condenser). The Thermal type sensors are connect-
ed to either J7 or J14 on the microboard, depending on
the vintage of the chiller. On new production chillers
before June 2009, they are provided connected to the
microboard J7 (See Figure 22 on page 70 ). On new
production chillers after June 2009, they are provided
connected to the microboard J14 (See Figure 23 on
page 71 ).
In order for the program to read the correct flow sensor
input, the Flow Switch setpoint on the OPERATIONS
Screen must be set appropriately in the procedure be-
low. The correct setting is determined by the software
version and the actual flow sensor connection point to
the OptiView Control Center as follows:
With software version C.OPT.01.20.307 (and earlier),
supplied before June 2009, the selections are ANA-
LOG or DIGITAL. Select ANALOG when the Ther-
mal type flow sensors are connected to the microboard
J7 (See
Figure 22 on page 70
). Select DIGITAL
when the Paddle type sensors are connected to the I/O
Board TB4 (See Figure 34 on page 102 ).
With software version C.OPT.01.21.307 (and later),
supplied after June 2009, the selections are J7, J14 or
TB4. Select J7 when the Thermal type flow sensors
are connected to the microboard J7 (See
Figure 24 on
page 72
). Select J14 when the Thermal type sensors
are connected to the microboard J14 (See Figure 24 on
page 72 ). Select TB4 when the Paddle type sensors
are connected to the I/O Board TB4 (See Figure 34 on
page 102
) and the Heating Condenser Water Paddle
type flow sensor is connected to the LTC I/O Board J20
(if equipped with the Heat Recovery option; see Figure
91 on page 236 ).
After the selection is made, the program will read the
flow sensor input at the selected connection point and
ignore the other connection points.
