Delay Timer
ELK-960
APPLICATION:
The ELK-960 is an economical and exible solution
for many general-purpose time delay applications.
The unit operates on 12 to 24 Volts D.C. and can be
selected for positive or negative trigger logic. Setup
is easy with thumb wheel adjustment between 1 and
60 seconds, a quick jumper setting converts the time
from seconds to minutes. The timer can be congured
to activate once for each trigger, or pulse as soon as
power is applied.
Features or Specications subject to change without notice.

TERMINAL DESCRIPTIONS
Positive power input. Connect a +12 to +24 Volts
D.C. source. Warning: Do not exceed +24 Volts
D.C., Damage will occur.
Negative power (ground) input. Connect to a
negative or ground terminal of the power source.
TGR Trigger voltage input. Connect a 4.5 to 24VDC
trigger source. Place jumper JP5 (TRIGGER
POLARITY) in the "+" position to trigger from a
positive voltage or in the "-" position to trigger
from a negative. The trigger voltage may be 4.5
to 24VDC, regardless of the main powered input
(12VDC to 24VDC).
N/O Normally Open side of the relay contacts. No
connection to COM when the relay is o.
COM Common or "pole" side of the relay contacts.
When the relay is o, COM is internally connected
with the N/C contact. When the relay is on, COM is
internally connected with the N/O contact.
N/C Normally Closed side of the relay contacts. This
terminal is internally connected with the COM
terminal when the relay is o.
NOTE: The ELK-960 automatically triggers (turns on) and runs through
a delay cycle when rst powered up. To reduce waiting time and
speed up installation, set jumper JP1 to SEConds and adjust R3 to 1
before applying power. Once power is applied, change the settings
as required.

SETTINGS AND JUMPER DESCRIPTIONS
R3 This knob is used to increase or decrease the delay time
from 1 to 60. Full clockwise is 1, halfway is 30, full counter-
clockwise is 60. The arrow is a reference point.
JP1 SEC = Delay time in seconds. Adjustable from 1 ~ 60.
1
MIN = Delay time in minutes. Adjustable from 1 ~ 60.
1
JP2 REPEAT = Adjustable pulse) Relay cycles ON / OFF at
delay time interval using a 50/50 duty cycle.
2
A trigger input will temporarily stop the cycle.
1-SHOT = Relay activates only once per trigger.
JP3 END = Relay turns o when triggered and back on
when delay time expires.
BEGIN = Relay turns on when triggered and back o
when delay time expires.
JP4 A = Delay time starts when trigger is removed.
B = Delay time starts when trigger is rst applied.
JP5 + = Selects positive polarity for the input trigger.
- = Selects negative polarity for the input trigger.
1
Times are approximate. When adjusted to the highest setting (60
minutes) the actual time delay will be slightly greater.
HINT: For a delay time in minutes, adjust and test with jumper
JP1 in the SEConds position. (I.E.: For a 15 minute delay, adjust
and test to 15 seconds) Then move jumper JP1 to MINutes. This
quickly provides a reasonable equivalent delay time in minutes.
2
A 50/50 duty cycle means the OFF and ON times will be equal.
OVERVIEW
The ELK-960 features adjustable delay time of one (1) second
to approximately sixty (60) minutes. It can be operated by
12 to 24 volts D.C. and can be triggered by a negative (-)
or positive (+) voltage. The operating mode and the relay
condition can be set as follows: BEGIN- Relay turns on when
triggered and back o when delay time expires. END- Relay
turns o when triggered and back on when delay time
expires. The delay time can start when the trigger is rst
applied (B mode) or when the trigger is removed (A mode).
The ELK-960 relay can be set to provide a single 1-SHOT
output or to REPEAT (pulse on and o). All options are
selected using easy to change mini-jumpers.
