Read this manual in its entirety before operating the POWERPOD-400 Power Supply/Totalizer. The
POWERPOD-400 is designed to operate with most Teledyne Hastings Instruments (THI) flow controllers
and meters. Read all wiring and power hookup instructions and understand the requirements prior to
using another manufacturer’s products with the POWERPOD-400. Insure that any product being
interfaced with the POWERPOD-400 is wired according to prevailing local safety and operational
standards before operating.
The WARNING label indicates important information that should be heeded for safe and proper
performance of the device.
The label, CAUTION, is used to indicate that damage to the power supply or equipment
connected to it could occur if directions are not followed. Warranty could be invalidated if the
instructions in this manual are not followed.
2.0 Safety

164-062009 PowerPOD 400 Page 7 of 42
The POWERPOD-400 serves as a convenient control center that can be rack-mounted using standard half-
rack hardware or can be used as a bench top unit. The POWERPOD-400 is equipped with a 4 X 20
character, vacuum fluorescent display (VFD). The display emulates a liquid crystal display in its
command structure but the VFD gives the unit a greater viewing angle and better visibility than available
with most conventional LED or LCD displays. The display can be set to four different brightness levels.
Use a lower brightness setting to extend the already long expected life time of the display. Use brighter
settings for viewing areas where ambient light may be too bright or cause glare, or where greater viewing
distances are required.
Most features are accessible via the membrane keys on the front panel. Consult the section on each
function to check its availability. Operators are guided through the many features and options by selecting
their choices from an intuitive menu structure.
FRONT PANEL LOCKOUT
ANALOG RANGE SELECTION
Analog signal and control ranges are operator selectable. The operator can choose between three different
DC ranges:
A fifteen (15) pin, high density, sub-miniature, D-type connector is provided for separate monitoring of
each channel’s analog transducer signal.
CAUTION: Consult the appropriate section for limits to the loading of these signals.
SERIAL COMMUNICATION
The POWERPOD-400 comes equipped with standard RS-232 and RS-485, serial communication. Most
functions, features, signals and alarms are accessible and modifiable via any remote computer.
3.0 Features
0 -5 VDC, 0-10 VDC or 4 -20 mA.
The Front Panel Lockout function is only available through serial communication. Manual
Overrides remain available during Lockout via a minimum number of keystrokes using
dedicated keys for this purpose and allow any command setting to be overridden in either the
high (open) or low (closed) state.
The following commands are manual commands only:
OPEN,
AUTO and CLOSE.
The status of these settings can be read via serial communication but they cannot be changed
except manually, from the front panel.

164-062009 PowerPOD 400 Page 8 of 42
POWER SELECTION
RATIO CONTROL
Ratio control is possible between channels using a familiar master/slave configuration. Channel one
(1) must be enabled as the master channel. Any combination of the remaining channels is possible
for slave channel assignment.
TOTALIZER
A Totalizer function is present for each channel with the capability of counting down from a set
point, counting up to a set point or continuous count up. The maximum count is ±999999 units.
When the set points are reached, a memory flag for each set point is set to a digital ‘1’ indicating a
Boolean ‘true’ value. The Totalizer set point flags must be polled via digital communication to be
read. Each flow channel has one low-limit and one high-limit set point available. These alarms are
available via open-collector, opto-isolated outputs on the rear panel as well as serial
communication.
POWER OUTAGES AND THE OVERRIDE CONDITION
In the event of a power outage, even one of short duration, the POWERPOD-400 is
designed to conduct a software reset. During the period of time in which the reset is
occurring, it will not accept or respond to any commands either manually or digitally
until the reset process is completed. After said reset, the POWERPOD-400 will have
remembered all previously entered set-points but all channels are designed to come up
in the “Override-CLOSEd” condition. For meters, this should have no affect on their
behavior. All analog-only, THI, flow controllers with normally-closed (NC) valves will
close and remain closed until operator intervention manually returns selected channels’
Override condition back to the AUTO mode.
For all other controllers, this means that the control signal (pins 5 to 14) of J1 through
J4 will return to the previously set level. For controllers not taking advantage of the
Override function (pin 8), these controllers will return to their normal, preset operating
condition unless other intermediary steps are undertaken. Controllers that are making
use of the override function (Pin 8) and have normally-open valves will be driven to the
fully open condition.
Power input is switchable between 100 VAC, 115 VAC and 230VAC (50 or 60 Hz) via
the rear panel. For the safety of the operator as well as the device, the correct power
level should be selected prior to connecting to the power mains. See the table
“POWERPOD-400 Specifications” in section 3.0 for the proper fusing when changing
power settings.

Each channel samples the incoming signal at a rate
corresponding to the preset A/D conversion rate in Hz. At
each sampling interval, the TOTALIZER function multiplies
the average signal, as a fraction of the full-scale value (5v, 10v
or 20 mA), times the span, or cal, value. This results in a rate
for that interval. Next, a time element factor is determined
according to the flow rate programmed for that channel as
follows.
For a time element of seconds, the factor is 1/10.
For minutes, the factor is 1/600.
Hours use a factor of 1/36000.
Each calculation is summed and stored for a TOTAL value.

164-062009 PowerPOD 400 Page 17 of 42
Example (See Graph):
A linear flow transducer with a DC output of 0 to 5 volts is calibrated for a maximum flow of 25 SLH.
The transducer is connected to one channel of a POWERPOD-400 which is CAL’d to read 25.000 at 5
volts input and has been programmed to display rate in SLH. The transducer is sending a constant 1.000-
volt signal to the POWERPOD-400. What is the total flow after 40 minutes?
During one sampling interval, the TOTALIZER reads the one-volt signal and calculates the fraction of the
possible full-scale value.
1 volt/5 volts or 0.20
The fractional signal value is multiplied times the CAL value
1/5 * 25 = 5
Then, because the channel’s programmed rate is in SLH (standard liters per hour), a factor of 1/3600 is
applied to the result.
5 * 1/36000 = 1.389 x 10^-4 standard liters per sampling interval.
A constant signal received over a 40 minute time period would amount to 40 minutes * 60 seconds * 10
samples per second = 24000 samples. The TOTAL would be
2.400 E03 * 1.389 E-04 = 3 1/3 Std Liters.
If no rate is programmed on that channel, The TOTALIZER function is disabled for that channel and the
display returns to its regular metering configuration.
To enable the TOTALIZER, press the MODE key. The MODE menu appears in the display. To select
TOTAL, press 2, and then ENTER. The TOTALIZER menu allows the operator to select the desired
channel. Press the number key that corresponds with the desired channel followed by ENTER. A
TOTALIZER menu is presented that allows the operator to go directly to displaying whatever the
Totalizer has currently stored as the total or to reset the counter. If DISPLAY is selected by pressing the
