7.4 Varying the Flow Rate - Manually
When the DLC is in Manual Mode, pump flow rate can be increased by pressing [UP]. The flow rate is
decreased by pressing [DOWN]. The DLC will display the corresponding value of the flow adjustment.
Do not adjust the DLC's hand-wheel while the power is off. This will cause the DLC to lose its zero
point and force a {ZERO CALIBRATION } at startup.
7.5 Mode
Pressing [MODE], switches the DLC’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}. If both ANALOG and MODBUS modes are active the mode key switches between all three. In
essence, this key acts like a local auto/manual switch.
7.6 Batch
The DLC 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 18).
