Emirel VD-04

TECHNICAL FEATURES AND REGULATIONS SP (SET POINT) Max set point (or min) divided in 10 parts to be set on the front by screwdriver. T Timer (0,05÷10 seconds standard) adjustable by means of a small screwdriver on the front. The set delay period starts as soon as the current exceeds the set value; at the end of this period the relay can go off. TC Initial timer (0,05÷10 sec. standard) adjustable by means of a screwdriver on the front. It makes the device “blind” at the voltage starting, in order to bypass the voltage spike if it occurs. This timer activates when the voltage overcomes Im (5% of the max range). (See Tab. A). TA (on demand) self-holding timer 1÷30 sec. It delays the alarm condition for the set time, even after the alarm origin has already gone out. MODE OF OPERATION The device can be programmed for max or min set point. At the start up of the machine, the eventual spike of voltage is bypassed by the timer TC. During normal operation the set point triggers after the delay time T. than 30m. INPUT Input resistance: > 8,5 kohm/V. Permanent overcoming of the value of RANGE (See Tab. C). Pin 3-5 (+ on pin 5) (fig. 3). OUTPUT: 5A 230Vac resistive load 7-6 NC Device not supplied 7-8 NO or in alarm SUPPLY 2VA - 50-60Hz ±10% 1-11: 115 Vac or 230Vac or 24Vac. INSULATION Galvanic separation it is given by the supply transformer. SIZE: 48x96x90 mm - undecal male base. Accessories available on request: E 171: hooks for flush mounting; E 172: undecal female base for DIN; M 13A: plexiglas protection IP 54-tight closure (for flush mounting); E 346: hold wire protecting from vibrations.
