General Operation
Time Delay
The Time Delay for Auto Batch Restart functions as follows: When a batch is completed, the next batch will
automatically start after the amount of time entered here. This time can be set from 1 to 99 seconds.
Flow Signal Timeout
The Flow Signal Timeout allows the user to enter a timeout of 0 to 99 seconds. If a batch is “Filling” and zero
flow persists for more than the user entered time then the batch will be aborted. This prevents over flows due to
faulty flow sensors and/or wiring.
Maximum Drain Time
The unit declares that a batch is “done” when the flow rate equals “0”. A flow rate may be present long after the
Preset Relay de-energizes due to slow reacting valves or leaky valves. The Maximum Drain Time allows the
user to enter an amount of time (0 to 99 seconds) to wait before declaring “Batch Done”. After the Preset Batch
quantity is reached, the unit will declare “Batch Done” when the flow rate is “0” or the Maximum Drain Time
has expired. The batch data will then be available for printing and datalogging.
Slow Start Quantity
The Slow Start Quantity is a function that allows an amount to be entered for a Slow Start up. This function
requires two stage valve control. RLY 1 (slow flow) will energize for Slow Start and RLY 2 (fast flow) will
energize after the Slow Start Quantity has been delivered. This helps reduce turbulence when filling an empty
container.
START, RESET/START and STOP, STOP/RESET
When configuring the control inputs, Control Input1 can be set for START or RESET/START. When set for
START, the unit will start batching when a signal is applied to Control Input1 or the front panel Start key is
pressed. A separate Reset signal must be used to clear the previous batch total. When set for RESET/START, the
unit will automatically reset then start when a signal is applied to Control Input1 or the front panel Start key is
pressed (provided that the pervious batch was completed). If a previous batch was stopped during a batch cycle,
the unit will Start from where it was stopped. Control Input 2 can be set for STOP or STOP/RESET. When set
for STOP, the unit will stop batching when a signal is applied to Control Input 2 or the front panel Stop key is
pressed. A separate Reset signal must be used to clear the batch total. When set for STOP/RESET, a running
batch will stop when a signal is applied to Control Input 2 or the front panel Stop key is pressed. If the unit is
Stopped or after a completed batch, the unit will reset when a signal is applied to Control Input 2 or the front
panel Stop key is pressed. NOTE: Applying a voltage level to Control Input 2 will inhibit all Start inputs in
either mode.
5.4.2 Password Protection for Batcher Mode
After an Operator and/or Supervisor Password is entered in the setup mode (see section 6.3, SETUP PASS
WORD submenu), the unit will be locked. The unit will prompt the user for the password when trying to per
form the following functions:
Clear Grand Total
Enter Menu
The Supervisor password should be reserved for supervisors. The Supervisor password will allow access to
restricted areas of the Setup and Test menus. The passwords are factory set as follows:
Operator = 0
Supervisor = 2000
5.4.3 Relay Operation in Batcher mode
Two relays are available for alarm outputs. Preset 1 (RLY1) is reserved for batch amount, Preset 2 (RLY2) is
reserved for prewarn. (see section 5.4 Batcher Operation for Relay 1 & Relay 2 functions) Preset 1 (RLY1) and
Preset 2 (RLY2) are easily accessible by pressing the PRESET 1 or PRESET 2 key on the front panel.
