User manual ELK PRODUCTS ELK-960

[. . . ] 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. Delay Timer ELK-960 APPLICATION: The ELK-960 is an economical and flexible solution for many general-purpose time delay applications. [. . . ] 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. 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. JP3 END = Relay turns when delay BEGIN = Relay turns when delay off when triggered and back on time expires. on when triggered and back off time expires. · Operating Voltage Range: 12 to 24 Volts D. C. · Packed In Reusable Poly Storage Box. SPECIFICATIONS: · Time Settings: 1 Sec to ~ 60 Min. · Relay Contact Rating: 7A @ 30 VDC. 10A @ 125 VAC. · Operating Voltage: 12 to 24 Volts D. C. · Size: 3"x2. 2"x1" (Fits Std. Snap Track). Features and Specifications subject to change without notice. JP4 A = Delay time starts when trigger is removed. = 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. (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. 2 A 50/50 duty cycle means the OFF and ON times will be equal. 828-397-4200 Voice 828-397-4415 Fax http://www. elkproducts. com email: info@elkproducts. com PO Box 100 · Hwy. 70W · Hildebran, NC 28637 · USA Instructions Printed On Inside 03/04 SAMPLE APPLICATIONS AND WIRING DIAGRAMS (Set jumpers as shown) 12/24 Volts DC Power Supply - 1 + TGR + DOOR STRIKE HOLD TIMER TIME 1 - 60 SEC MIN R3 JP1 TRIGGER POLARITY 12/24 Volts DC Power Supply - 2 + TGR + MAGLOCK RELEASE TIMER TIME 1 - 60 SEC MIN REPEAT 1-SHOT END BEGIN R3 JP1 TRIGGER POLARITY ELK-960 Delay Timer ELK-960 Delay Timer 12/24V DOOR STRIKE 1-SHOT END BEGIN + N/O Pushbutton JP5 JP3 12/24V MAGLOCK N/O COM N/C K1 TRIGGER MODE A B LED JP4 + N/O Pushbutton N/O COM N/C K1 TRIGGER MODE A B LED JP4 Used to extend the release time of an access control device or to manually activate a door strike release device. The trigger is activated by a contact closure or a N/O pushbutton and the door strike remains activated (door open) after the button is released for the delay time set up in the ELK-960. 12 Volts DC Power Supply Used to extend the release time of an access control device or to manually activate a door maglock release device.
