Startup and Shutdown Procedures
Table 87: Flow Volume Calculation
Figure 99: Teach Adjustment Complete
In Step 3, the ‘Teach’ function re-adjusted the flow switch set
point (SP) while flow was at the minimum desired operating
flow. The chiller will not operate at this flow because the
flow switch is OPEN after performing the ‘Teach’ function.
The benefit of the ‘Teach’ function is to quickly set the set
point within the desired operating range. Additional ‘manual’
adjustment of set point is required in order to allow for chiller
operation at this minimum flow. The ‘+’ and ‘-’ buttons on the
face of the flow switch allow for the manual adjustment of the
SP. Pressing the ‘+’ button reduces the flow set point while
pressing the ‘-’ button increases the flow set point. Each button
press, ‘+’ or ‘-‘, changes the flow set point by 2.5 cm/s.
Step 4:
Press the ‘+’ button until LED ‘9’ begins to flash, as
shown in
. Opening of flow switch should now occur
at approximately 80% to 90% of minimum flow.
Figure 100: Upper Range of Minimum Flow
Step 5:
Once the SP is set, it is recommended that the
sensor be locked to avoid inadvertent readjustment. This
can be performed by pressing both the ‘+’ and ‘-’ buttons
simultaneously for 10 seconds. The indication goes out
momentarily indicating the unit is locked. To unlock, the same
procedure is performed to toggle to unlocked.
NOTE:
1. The LED window display on flow switch represents
a velocity range of 50 cm/s. The window centers on
the set point (SP). For example, if the SP was set to
200 cm/s, then the LED labeled ‘0’ would represent
a velocity of 180 cm/s when lit and the LED labeled 9
would represent a velocity of 230 cm/s when lit.
2. Each LED represents 5 cm/s, or two presses of the
‘+’ or ‘-’ buttons.
3. When power is initially applied to the flow switch,
all green LEDs light and go out step by step. During
this time, the output is closed. The unit is in the
operating mode.
4. When making manual adjustments to the set point
(SP), if no button is pressed for 2 seconds, the unit
returns to the operating mode with the new set value.
