PROGRAM RATE METER (cont.)

Sub Menu 36 - Rate Meter Zero Time-out

The rate meter displays zero rate when the time interval between input pulses exceed the programmed
rate zero time. The timer can be set from 1 to 15 seconds. Use the Clear, number and Enter keys to
enter a new timer value.

Sub Menu 37 - Rate Display Header

The rate units of measure (up to three characters) can be programmed into the unit and will be shown
along with the rate value and rate setpoints on the display. (The totalizer display does not show a unit
of measure.) If the rate data exceeds four digits, the rate header will be shifted off the display one
character for each additional digit.

Use the < and > keys to cause the selected character to blink. Then use the ^ key to scroll through the
alphabet. Blank (no character) is between Z and A.

PROGRAM OTHER

Sub Menu 41 - Setpoint Lock

The totalizer and rate meter hi/lo setpoints can be selectively locked to their current value by locking
them in the program mode. Use number keys 2, 4 and 5 to select a setpoint (total, low alarm or high
alarm, respectively). Use the up arrow key to select if the setpoint should be locked to it’s current
value or left open for operator changeability. (The factory default is all keys open.)

Sub Menu 42 - Password

A password can be programmed into the unit to provide password access to the program mode. The
unit as it comes from the factory does not require the entry of a password to gain access to the
program mode. This is accomplished by programming all zeros into the password data field. Entering
a number from 1 to 6 digits in length into the password data field activates the password access to the
program mode.

In the run mode of operation, a means of entering into the program mode is provided if the password
was lost. When the unit prompts the user for PASSWORD, key in 9999999999 Enter.

Sub Menu 43 - Communication Baud Rate and Parity

The baud rate and parity are set in this menu. Enter a baud rate of 300, 600, 1200, 2400, 4800, 9600
or 19200 by using the Clear, number and Enter keys. Enter EVEN, ODD or SPACE parity by using
the up arrow key.

Sub Menu 44 - Unit ID number and Response Delay Time

The unit identification number is set in this menu. Each unit on the communication bus must have a
unique identifying number, 1 through 255. Enter the units ID by using the Clear, number and Enter
keys. The length of time before the control response to communication requests can set to
accommodate various types of computer equipment. Delay times of 0, 10, 100 and 500 milliseconds
can be selected by using the up arrow key.

Sub Menu 45 - Maximum Count Input Speed

The maximum count input speed is selected in this menu. Use the up arrow key to select from: FAST
