Characteristics
• relay designed for monitoring DC and AC voltage in three ranges
• the relay controls the size of the voltage in two independent levels (Umin, Umax)
• setting the monitored level Umax (in % of range)
• setting the monitored level Umin
(in % of range - for HRN-42 -function WINDOW),
(in % of the set upper limit - for HRN-41 - function HYSTERESIS)
• adjustable function "MEMORY"
• function of second relay (independently / in parallel)
• adjustable delay for eliminating short-term outages and surges for every level
independently
• galvanically separated power supply from monitoring inputs
• output contact 2x switching 16 A / 250 V AC1 for each monitored voltage level
• in 3-MODULE design, fi xing to DIN rail

13
- if alternating current voltage is connected when measuring DC or direct current voltage is connected when measuring AC, or if
14
there is incorrect polarity of DC, a polarity error is reported - both red LEDs fl ash and relays are open
15
8. Memory
- when the memory is switched on, the indication of an error status is maintained until the moment of reset by means of a button
(if in between, the OK status occurs)
9. Output
- position 1 - both relays work simultaneously (they open in error status)
16
- position 2 - the relays work independently - relay 15-16-18 corresponds to the upper level (Umax), relay 25-26-28 corresponds to
the lower level (Umin)
10. Hysteresis - setting the hysteresis upon returning from an error state
11. t1 - time delay for Umax
12. Adjusting upper level - Umax
13. Button RESET
14. t2 - time delay for Umin
15. Adjusting bottom level - Umin
