ELK 960 User Manual

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.

APPLICATION:

The ELK-960 is an economical and flexible 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 thumbwheel adjustment between 1 and 60 seconds, a quick jumper setting converts the time from seconds to minutes. The timer can be configured to activate once for each trigger, or pulse as soon as power is applied.

ELK-960

Economical Time Delay Relay Module

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 terminal 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

1-SHOT = Relay activates only once per trigger.

JP3 END = Relay turns off when triggered and back on

BEGIN = Relay turns on when triggered and back off

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.

03/04

delay time interval using a 50/50 duty cycle. A trigger input will temporarily stop the cycle.

Delay is starte d when the door is opened. If the door

remains opened after the time delay has expired th e relay

will turn on and remain on until the door is closed. If the door

is closed before the time delay expires the ELK-960 is reset

awaiting another input from the door contact.
