LDB-ST1LE Batcher
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 Input 1 or the front panel Start key is
pressed. A separate Reset signal or CLEAR key depression 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 or CLEAR
key depression 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 and override 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
PASSWORD Sub-menu), the unit will be locked. The unit will prompt the user for the password when trying
to perform 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
NOTE: A password of "0" should not be used since it will leave the unit unlocked and open to accidental
changes.
5.4.3 Relay Operation in Batcher mode
Up to four relays are available (two standard) 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 PRE 1 or PRE 2 key on the front
panel. Preset 3 and Preset 4 are accessible by pressing the 4 or 9 keys.
Relays 3 and 4 can be assigned to trip according to rate, total, overrun or alarm. When Rate is selected the
relays can be programmed for low or high alarms. When N.A (not assigned) is selected, the relays may be
tripped via serial commands. Alternately, Preset 2, 3 or 4 may be used to enter alternate information and can
be printed in the print list for transaction history.
5.4.4 Pulse Output in Batcher mode
The isolated pulse output (open collector) is assigned to Volume Total. The pulse output duration can be set
for 10mS (50 Hz max) or 100mS (5 Hz max). A pulse output scale factor (pulse value) can be set to scale
the pulse output. The pulse output is ideal for connecting to remote totalizers or other devices such as a PLC.
See section 1.3 for electrical specifications.
5.4.5 Analog Output in Batcher mode
The analog output is menu assignable to correspond to the Volume Rate or Volume Total. The analog
output is ideal for "trend" tracking using strip chart recorders or other devices.
