SWITCH SET-UP
S1 - DIS.RST.:
Disables front panel reset.
EN. RST.:
Enables front panel reset.
S2 to S5:
These are the mode select DIP switches.
See Modes of Operation for the switch settings of a specific mode.
S6 - 0.00:
Sets the timer to display two decimal places.
0.000:
Sets the timer to display three decimal places.
S7 - Sec.:
Sets the timer to display in seconds.
Min.:
Sets the timer to display in minutes.
MODES OF OPERATION FOR DUAL PRESET LNXNT TIMER
MODE 0 LATCHED OUTPUTS AT PRESET, MANUAL RESET TO
ZERO
The unit times from zero, when preset 1 is reached,
output 1 turns on and time continues to accumulate.
When preset 2 is reached, output 2 turns on and time
continues to accumulate. When a manual reset is performed, the time
resets to zero, the outputs turn off, and the cycle starts again.
MODES OF OPERATION, DIP SWITCH SET-UP
The DIP switches for the various operating modes are accessible from the rear of the unit.
Notes
1. A manual reset, either from the front panel reset (if enabled) or remote reset overrides any condition or state of the timer and
begins the cycle again.
2. In modes four, five, twelve, and thirteen, the output may appear to be latched if the time delay is longer than the time required
for the timer to reach the preset point or zero.
