APPLICATION:The ELK-960 is an economical and flexiblesolution for many general-purpose time delayapplications. The unit operates on 12 to 24Volts D.C. and can be selected for positive ornegative trigger logic. Setup is easy withthumbwheel adjustment between 1 and 60seconds, a quick jumper setting converts thetime from seconds to minutes. The timer can beconfigured to activate once for each trigger, orpulse as soon as power is applied.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 off

when delay time expires. END- Relay turns off when

triggered and back on when delay time expires. The

delay time can start when the trigger is first 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 off). All options

are selected using easy to change mini-jumpers.

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 nega-

tive 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 con-

nection to COM when the relay is off.

COM Common or "pole" side of the relay contacts. When

the relay is off, 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 termi-

nal when the relay is off.

NOTE: The ELK-960 automatically triggers (turns on) and runs

through a delay cycle when first 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.

MIN = Delay time in minutes. Adjustable from 1 ~ 60.

JP2 REPEAT= (Adjustable pulse) Relay cycles ON / OFF at

delay time interval using a 50/50 duty cycle.

A trigger input will temporarily stop the cycle.

1-SHOT = Relay activates only once per trigger.

JP3 END = Relay turns off when triggered and back on

when delay time expires.

BEGIN = Relay turns on when triggered and back off

when delay time expires.

JP4 A = Delay time starts when trigger is removed.

B = Delay time starts when trigger is first applied.

JP5 + = Selects positive polarity for the input trigger.

- = Selects negative polarity for the input trigger.

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. (IE: 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.

A 50/50 duty cycle means the OFF and ON times will be

equal.
