Helios Large Display Analog Input Batch Controller Instruction Manual
7
Totalizer
Calculates total based on rate and
field programmable multiplier to
display total in engineering units.
Time base must be selected
according to the time units in which
the rate is displayed.
Grand Totalizer
Rollover
Grand totalizer rolls over when
display exceeds 999,999,999.
Relay status reflects display.
Grand Total
Alarms
Up to seven, user selectable under
setup menu. Any set point can be
assigned to grand total and may
be programmed anywhere in the
range of the controller for grand
total alarm indication. Relay 1
should always be assigned to
batch.
Programmable
Delay
On Release
0.1 and 999.9 seconds; applied to
the first relay assigned to total or
grand total.
If the controller is programmed to
reset total to zero automatically
when the preset is reached, then a
delay will occur before the total is
reset.
Grand Total
Reset
Via front panel button, external
contact closure on digital inputs,
automatically via user selectable
preset value and time delay, or
through serial communications.
Grand Total
Reset Password
Grand total passwords may be
entered to prevent resetting the
grand total from the front panel.
Non-Resettable
Grand Total
The grand total can be
programmed as a non-resettable
total by entering the password
“050873”.
Caution!
Once the Grand Total
has been programmed
as “non-resettable” the
feature
cannot
be
disabled.
Relays
Rating
2 or 4 SPDT (Form C) internal
and/or 4 SPST (Form A) external;
rated 3 A @ 30 VDC and 125/250
VAC resistive load; 1/14 HP (
≈
50
W) @ 125/250 VAC for inductive
loads
Noise
Suppression
Noise suppression is
recommended for each relay
contact switching inductive loads;
see page 17 for details.
Deadband
0-100% of span, user
programmable
1
Alarms are active only when the batch is running.
High or Low
Alarm
User may program any alarm for
high or low trip point.
Unused alarm LEDs and relays
may be disabled (turn off).
Relay Operation
Primary Functions:
Batch Control
Automatic (non-latching)
1
Sampling (based on time)
Off (disable unused relays and
enable Interlock feature)
Manual on/off control mode
Secondary Functions
2
:
Pump alternation control (2 to 4
relays)
Latching (requires manual
acknowledge)
Relay Reset
User selectable via front panel
buttons or digital inputs
1. Automatic reset only (non-
latching), when the input
passes the reset point.
2. Aut manual reset at
any time (non-latching)
3. Manual reset only, at any time
(latching)
4. Manual reset only after alarm
condition has cleared (latching)
Note: Front panel button or digital
input may be assigned to
acknowledge relays
programmed for 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.
Isolated 4-20 mA Transmitter Output
Output Source
Process variable (PV), max, min,
set points 1-8, Modbus input, 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% of span ± 0.004 mA
2
These operations are not functional when the unit is
being used as a batch controller with total set to yes.
