FIRST 8 SWITCHES ARE FOR TIME SETTING
4. DIP SWITCH SETTING
There are a total of 13 Dip Switches on the TMR2. The first 8 marked with binary numbers
are for time setting and are explained in section 3. The next 5 select functions as follows:
4.1 SW1: TIME UNIT SETTING
In the factory set condition (off), the time value set on the 8 time setting Dip Switches is
expressed in seconds. Turning the switch on allows time setting in minutes.
4.2 SW2: TRIGGER SWITCH LOGIC
Several of the operating modes (off delay, toggle and pulse output) require triggering from
an external switch. The switch connects the trigger terminal (T) to the board's "+" terminal.
In the factory set position of SW2 (off), a normally open external switch is used for triggering
so that when terminal T is closed to terminal "+", the timer is triggered. Turning the
switch on permits the use of a normally closed external switch. When the connection
between terminal T and "+" is broken, the unit is triggered.
4.3 SW3 AND SW4: MODE SETTING MATRIX
These switches are set in a matrix yielding 4 different operating modes for the TMR2. The
factory set position is on delay. The modes are described in detail in section 6. The matrix
settings are:
SW3 ON; SW4 ON: ON DELAY MODE
SW3 OFF; SW4 ON: ONE SHOT MODE
SW3 ON; SW4 OFF: TOGGLE MODE
SW3 OFF; SW4 OFF: OFF DELAY MODE
The TM-2 actually provides 7 different operating modes with methods other than Dip settings
being used to establish the other 3. Make sure you read the description of your mode in
Section 6 as the setting of Dip Switches 3 and 4 is only part of the mode selection process.
