NOVATEK-ELECTRO LTD Research-and-Manufacture Company MULTIFUNCTIONAL TWO-CHANNEL TIME DELAY RELAY REV-201М USERS MANUAL
-2- This present manual contains necessary information about application, main operation principles and adjustment setting for the two-channel electronic time delay relay REV-201M (hereinafter REV-201М). 1 GENERAL DESCRIPTION AND OPERATION 1.1 APPLICATION REV-201M is designed for the commutation of electrical circuits of 240V 50Hz AC as well as 24 – 100V DC electrical circuits with the adjustable time delay setting.
-3- Electrical characteristics for the Output terminals Cos Maximal current at U~250В 7А 1,0 Maximal capacity 1250 ВА Maximal Voltage ~ 250 В Maximal Current at UDC=28V 3А Arbitrary mounting position Standard 35 mm DIN rail mounting 1.2.2 Front panel view and outer dimensions are shown on figure 1.
-4- approximately 250 milliseconds. This happens due to smooth voltage increase on the power supply source of REV-201M. Kindly see Figure 2 below for more details. V ms 1 – Voltage growth curve on the REV-201M input power supply 2 – Curve showing the triggering time for the output terminals when the REV-201M has minimal (zero) time delay settings. Figure 2 – Initialization time for REV-201M after the power supply is given to the device input terminals 1.2.3.
-5- When the Turn ON time interval comes to an end REV-201M turns OFF the load and REV-201M switches to the idle mode. LED color indicator changes to GREEN. 1.2.3.3 Cyclic operation mode Position of DIP switches “A” V terminals Figure 5 – Cyclic operation diagram Each Channel work independently. Timing countdown on each channel starts from the moment of power supply application to the input terminals «L1-N» (Channel 1); «L2-N» (Channel 2).
-6- - fixed. On special customer request for the algorithm “START-PAUSE-START” it’s possible to change the timing intervals and delays as per requirement REV-201M has internally preprogrammed block that doesn’t allow to turn ON the power load on Channel 2 until output contacts of Channel 1 are being closed (ON). 2 GENERAL USE AND APPLICATION 2.1 FIRST START UP PREPARATIONS 2.1.
-7- Adjustment of time intervals should be made with the use of potentiometer knobs 2, 3 (Figure 1) for the Channel 1 and potentiometer knobs 7, 8 (Figure 1) for the Channel 2.
-8- 3.2 It is recommended to perform technical maintenance every 6 months of use. Look at the case of REV-201M and make sure that there are no dents or any other mechanical damages. Make sure that all the wires are tightened well and properly connected and pay attention to the absence of burned contacts. 4 PRODUCT LIFETIME WARRANTY AND STORAGE CONDITIONS Manufacturer assures 10 years operation lifetime for the REV-201M. On the expiration of this time kindly contact to the manufacturer.
