FLASH TIMER ANNUNCIATOR

This parameter allows the Timer annunciator (TMR) to flash when the Timer
is running or stopped/inhibited. Select

TIMER INPUT STATE AT POWER-UP

Determines the "Run/Stop" State of the Timer at Power-up. This parameter
does not apply to
timer input operation.
- Timer Stopped at power-up, regardless of prior run/stop state
- Timer assumes the same run/stop state it was in prior to power-down
6.2 MODULE 2 - U
Module 2 is the programming module for the rear terminal User Inputs and
front panel Function Keys.
Three rear terminal User Inputs are individually programmable to perform
specific meter control functions. While in the Display Mode, the function is
executed when the User Input transitions to the active state. Refer to the User
Input specifications for active state response times. Certain User Input functions
are disabled in "Full" Programming Mode. User Inputs should be programmed
while in the inactive state.
Three front panel Function Keys, F1, F2 and RST, are also individually
programmable to perform specific meter control functions. While in the Display
Mode, the primary function is executed when the key is pressed. Holding the
F1 or F2 Function Keys for three seconds executes a secondary function. It is
possible to program a secondary function without a primary function. The front
panel key functions are disabled in both Programming Modes.
In most cases, if more than one User Input and/or Function Key is
programmed for the same function, the maintained (level active) functions will
be performed while at least one of those User Inputs or Function Keys are
activated. The momentary (edge triggered) functions are performed every time
any of those User Inputs or Function Keys transition to the active state.
Some functions have a sublist of parameters, which appears when
pressed at the listed function. A sublist provides yes/no selection for Display
Values or Setpoints which pertain to the programmed function. The function
will only be performed on the parameters entered as
Input or Function Key is configured for a function with a sublist, then that
sublist will need to be scrolled through each time, in order to access any
parameters for the User Inputs or Function Keys which follow.
NO FUNCTION
With this selection, NO function is performed. This is the factory setting for
all user inputs and function keys except the Reset (RST) Key.

PROGRAMMING MODE LOCK-OUT

Programming Mode is locked-out, as long as activated (maintained action).
In Module 3, certain parameters can be setup where they are still accessible
during Programming Mode Lock-out. A security code can be configured to
allow complete programming access during User Input lock-out. This parameter
does not apply to the function keys. Program only one user input for this function.
EXCHANGE PARAMETER LISTS
Two lists of parameter entries are available for the Timer/Counter Start and
Stop Values; Setpoint On/Off and Time-Out Values; and Setpoint Daily On/Off
is
Occurrence (for Real-Time Clock option). The two lists are named
. If a User Input is used to select the list, then
the User Input is in the inactive state and
Input is in the active state (maintained action). If a front panel Function Key is
used to select the list, then the list will toggle for each key press (momentary
action). The display will only indicate which list is active when the list is
changed or when entering any Programming Mode.
