120 VAC Only
E48329
In the timer mode, the 385 can be programmed to cover the overall
span of 001 SEC to 999 HR in nine ranges, and can be programmed to
time in Hours:Minutes and Minutes:Seconds In the counter mode, it can
cover the overall span of 1 to 99,900 counts in two ranges
MULTIPLE RELAY ACTIONS: The relationship between the 385’s two
DPDT relays, Relay 1 and Relay 2 can be programmed for any of the four
modes of operation to satisfy virtually any control scheme
MULTIPLE STARTING OPTIONS: The 385 can be easily programmed to
start with a momentary or sustained start signal The star t signal can
also be set for a voltage or no voltage starting condition
NEW TIMING AND COUNTING MODES: The 385 has two new modes of
operation The flip-flop timer/counter with batch, which can be pro-
grammed to function as a flip-flop that will stop after a certain number
of cycles or a time span The other new flip-flop function is a standard
flip-flop with a programmable dwell between the relays
DISPLAY: The display is an LED dual display which can be programmed
to run UP to or DOWN from the set point The lower display shows the
preset selected to view and the upper display shows the cycle progress
NON-VOLATILE MEMORY: The 385 retains its entire program and preset
time/count periods even when there is a loss of power No batteries are
required
REAL-TIME COMPUTATIONS: The 385’s microcomputer instantly recom-
putes time/count-out when there is a change in the set point during a
cycle This allows you to shorten a cycle without loss of accuracy
COMPACT, PLUG-IN AND DUST-TIGHT: Packaged in a 72mm
housing, the 385 takes 40% less panel space than conventional timers
A true plug-in design, it can be replaced in seconds without disturbing
housing or wiring Fully gasketed and sealed, it is dust tight in panel
mounted installations SETUP: Setup of the 385 is accomplished using
16 DIP switches which are located inside the unit These DIP switches
give a visual indication of how the Controller is setup, and eliminates the
use of complex programming codes

After you have setup the Controller by programming the DIP switches
you must first set DIP switch (8) on the right bank to program mode,
this allows you to set the presets 1, 2 and 3, in seconds, minutes, or
hours You must press the “select” button to choose the preset to se-
lect To choose the time range you must select the timing bar ” “ and

in the bottom position, when used as a counter it will display as a “ ”
After each selection is made you must press the “enter” button
Preset 3 can be set up as a count or time input regardless if it is set up
as a counter or a timer/counter in Flip-Flop with batch mode
When setup as a standard timer (DIP switches 2 and 3 up on left bank)
you may program the decimal point by scrolling past the left digit and
press the up scroll button, this will place the decimal point in the 2 pos-
sible places, when finished press the “enter” button and set back to run
mode When the 385 is in the run mode the time from each preset can
only be adjusted in the time range with the decimal position you chose
while in the program mode
For users who wish to have no changes allowed in the run mode – see

energized when Relay 2 energizes. Both relays
drop out simultaneously.

*Note: Relay arrangement 1 and 2 are shown in single cycle only, when used in repeat cycle the relationship between the relays changes,
the process restarts after preset 2 The microprocessor automatically calibrates the timer for 50 or 60Hz power operation, there are no
switches or jumpers to set
