Teledyne powerpod 400 instruction manual Features, Front Panel Lockout

3.0 Features

The POWERPOD-400serves 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-400is 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

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.

ANALOG RANGE SELECTION

Analog signal and control ranges are operator selectable. The operator can choose between three different DC ranges:

0 -5 VDC, 0-10 VDC or 4 -20 mA.

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.

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.
