Multi-Function Timer / Sensor Relay DMC User Information English translation DMC - the microcontroller-controlled multi-function timer provides all common functions and time ranges in one device: 16 functions: On-delay, signal off-delay, signal on- and off-delay, one shot actuation during starting, one shot actuation during stopping, wipe contact during starting and stopping, flicker, one shot actuation, pulse shaping, each in some cases inverted too, electronic sensor. 1 or 2 contacts Design with 1 or 2 change-over contacts, 2nd change-over contact optionally as instantaneous or 2nd time closing contact. Installation Time ranges and functions are set at a 9-position DIL switch on the side of the device. A1-A2 are operating voltage connections for AC 230V (or AC 115V), B1-B2 for DC 12-30V. Functions and time ranges cannot be altered once the operating voltage has been applied. The devices are available with one or two change-over contacts. In the design with two change-over contacts the second contact can be optionally switched as a time closing or instantaneous contact (switch 1): 1 ON OFF On: 2nd contact 25-26/28 as instantaneous contact Off: 2nd contact 25-26/28 as time closing contact The functions "signal off-delay", "signal on- and off-delay", "wipe contact during stopping", "one shot actuation during starting and stopping", "pulse shaping" are controlled via a potential-free contact at Y1-Y2. Every change of state at Y1-Y2 directly affects the connected time function irrespective of whether a preceding reset time has elapsed or not. All other time functions start when the operating voltage is applied. Electronic sensor With the "electronic sensor" function the relay picks up when the value of an electrical resistance connected to terminals Z1-Z2 drops below a certain level. The DMC can be used as a contact protection relay, sensor switching amplifier, temperature probe (with external PTC/ NTC resistor) or twilight switch (with external LDR resistor) in this mode of operation. If a remote potentiometer is connected the bridge between terminals Z1-Z2 must be removed and the potentiometer on the front set to maximum. Time ranges The desired time range is determined according to the following table using the selector switch 6-9. The time at the end position of the potentiometer t is given. Contact 15-16 (25-26) switches after operating voltage is applied to A1-A2 (or B1-B2) and time lapse to 15-18 (25-28). 2 3 4 5 Remote potentiometer One shot actuation (starting) Contact 15-16 (25-26) switches after operating voltage is applied to A1-A2 (or B1-B2) for the duration of the set time to 15-18 (25-28) A1-A2 When voltage is applied to A1-A2 (B1-B2) the timed contact turns on and off repeatedly, starting with the pause time The function can be inverted with switch 2 = ON (start with working time). Contact configuration One shot actuation Contact 15-16 (25-26) switches after operating voltage is applied to A1-A2 (or B1-B2) and time lapse t for 0.5 sec. to 15-18 (25-28). 2 3 4 5 The function can be inverted with switch 2 = ON.

Multi-Function Timer / Sensor Relay DMC User Information English translation Signal off-delay Contact 15-16 (25-26) switches after the potential-free contact closes at Y1-Y2 to 15-18 (25-28). When Y1Y2 opens the off-delay time t starts, after which the contact switches back to 15-16 (25-26).. One shot actuation during starting and stopping Contact 15-16 (25-26) switches to 15-18 (25-28) for the time t after the potential-free contact closes at Y1Y2. Once Y1-Y2 opens the contact 15-16 (25-26) switches to 15-18 (25-28) for the duration t. 2 3 4 5 Pulse shaping Contact 15-16 (25-26) switches...
