Model PD6210 & PD6310 Batch Controllers Instruction Manual
14
RELAY
OPERATION Batch control
Automatic (non-latching)
1
Sampling
Off (disable unused relays and enable Interlock feature)
Manual on/off control mode
Secondary Functions
2
Pump alternation control (2 to 8 relays)
Latching (requires manual acknowledge)
RELAY RESET User selectable via front panel buttons, digital inputs, or PC
1. Automatic reset only (non-latching), when the input
passes the reset point or total is reset to zero.
2. Automatic + manual reset at any time (non-latching)
3. Manual reset only, at any time (latching)
4. Manual reset only after alarm condition has cleared (L)
Note: Digital inputs may be assigned to acknowledge relays
programmed for manual reset. It is not recommended to
change the functions of front panel buttons to manual reset.
ALARM TIME
DELAY 0 to 999.9 seconds, on & off relay time delays
Programmable and independent for each relay.
FAIL-SAFE
OPERATION Programmable and independent for each relay.
Note: Relay coil is energized in non-alarm condition.
In case of power failure, relay will go to alarm state.
ALARM AUTO
INITIALIZATION When power is applied to the controller, relays will reflect
the state of the input to the controller.
1
1. Alarms are active only when the batch is running.
2. These functions are not functional when the unit is being used as a batch
controller with total set to yes.
Isolated 4-20 mA Transmitter Output
OUTPUT
SOURCE Rate/process, total, grand total, max, min, set points 1-8,
Modbus register, or manual control mode
SCALING RANGE 1.000 to 23.000 mA for any display range.
CALIBRATION Factory calibrated: 4.000 to 20.000 = 4-20 mA output
ANALOG OUT
PROGRAMMING 23.000 mA maximum for all parameters:
Overrange, underrange, max, min, and break
ACCURACY ± 0.1% FS ± 0.004 mA
TEMPERATURE
DRIFT 0.4 µA/ C max from 0 to 65C ambient,
0.8 µA/ C max from -40 to 0C ambient
Note: Analog output drift is separate from input drift.
ISOLATED
TRANSMITTER
POWER SUPPLY Terminals I+ & R: 24 VDC  5% @ 40 mA maximum; may
be used to power the 4-20 mA output or other devices.
