2. SETTING SWITCHES:
The three digits are set with the rotary switch knobs located beneath each digit. These knobs can be
rotated in either direction (CW or CCW), and they are "pull" removable if digit set security is desired.
Changing one or more digits, during timing, will instantly be reflected by an equivalent change in the
timer's display. Setting all three digits to zero will cause instant time-out of the timer.
B. Internal Settings
THE 365 DIGITAL DISPLAY TIMER MUST BE REMOVED FROM ITS HOUSING TO ALTER ANY OF
THE FOLLOWING SETTINGS.
1. TIME RANGE:
Decimal Point Location
can be changed with the white plastic lever mounted behind the front face of
the timer. This lever moves into three positions. With finger force you can change its position and at
the same time observe the front of the timer. NOTE - this procedure sets the decimal point
electronically as well as visually.
Time Units (Sec/Min/Hr)
are set by moving a small width metal arm in a slotted arc on the side plate
nearest to the units (Sec/Min/Hr) window. By depressing this arm slightly with a pencil or pen point, it
can be moved to a new position. The time units physically change in the timer's face and the timer is
electronically switched to the new units as well.
2. LINE FREQUENCY:
To set the proper line frequency, connect the jumper wire to either the 50 HZ or 60 HZ pin. These
pins are clearly marked on the side of the timer.
NOTE:
THE TIMER CHASSIS AND THE HOUSING ARE POLARIZED SO THAT THE CHASSIS CANNOT
BE INSERTED INTO ITS HOUSING UPSIDE-DOWN. IF THE TIMER IS FORCED INTO THE HOUSING
UPSIDE-DOWN DAMAGE WILL RESULT.
4.1.6 Main Fuse
This fuse, located in a fuse block within the controller enclosure, protects the controller and sampler components
against overloads and short circuits.
For 110/120 VAC, 1PH operation use ONLY a Buss Type FNM, 4 Amp, 250 Volt Slo-Blo fuse or equal.
For 220/240 VAC, 1PH operation use ONLY a Buss Type FNM, 2 Amp, 250 Volt Slo-Blo fuse or equal.
Optional - For standard sampling systems with excess sample leg or auger.
For 110/120 VAC, 1PH operation use ONLY a Buss Type FNM, 10 Amp, 250 Volt Slo-Blo fuse or equal.
For 220/240 VAC, 1PH operation use ONLY a Buss Type FNM, 5 Amp, 250 Volt Slo-Blo fuse or equal.
4.1.7 Index Relay IR-1
This mechanical latching relay signals the sampler motor starter coils. When the relay coil receives a momentary
signal from the timer T-1 the maintained switch contacts change to the alternate position. Upon changing position
the opposite motor starter coil receives power, the motor starts and a sample is taken.
