7.4 Varying the Flow Rate - Manually
When the DLCM is in Manual Mode, pump flow rate can be increased by pressing [UP]. The flow rate is
decreased by pressing [DOWN]. The DLCM will display the corresponding value of the flow
adjustment.
If you attempt to adjust the DLCM’s hand-wheel while it is under power, the DLCM will re-adjust back
to the position specified by its programming. The hand-wheel is for emergency manual override only.
Refer to Section 12.1.
Do not adjust the DLCM's hand-wheel while the power is off. This will cause the DLCM to lose its
zero point and force a {ZERO CALIBRATION } at startup.
7.5 Mode
Pressing [MODE], switches the DLCM’s operating mode. If the ANALOG MODE is set to ACTIVE,
then pressing [MODE] will switch between {MANUAL MODE} and {ANALOG MODE}. When
MODBUS MODE is set to ACTIVE, pressing [MODE] will switch between {MANUAL MODE} and
{MODBUS MODE} In essence, this key acts like a local auto/manual switch.
7.6 Batch
The DLCM is capable of following up to three (3) different batch programs. The batches operate in two
modes: One Time Only and Repeating.
When Daylight Savings is set to Auto Change, use caution when setting up batches that run through
or start or stop in the time change over periods where one full hour either doesn’t exist at all or
occurs twice consecutively. If you are in doubt, set the {DAYLIGHT SAVINGS} option to [NO].
(Refer to Section 7.2.3 – Set Time & Date)
7.6.1 One Time Only
The One Time Only batch will start at a specified time and run for a specified duration at a specified
flow rate that you define (refer to Figure 21).
