UNEXPECTED EQUIPMENT OPERATION No galvanic isolation between supply terminals and control inputs. Failure to follow these instructions can result in death, serious injury, or equipment damage.
A.C. Load Curve 1 Electrical durability of contacts on resistive loading millions of operating cycles X Current broken in A Y Millions of operating cycles A.C. Load Curve 2 Reduction factor k for inductive loads (applies to values taken from durability curve 1). X Power factor on breaking (cos ϕ) Y Reduction factor k Example: An LC1-F185 contactor supplied with 115 V/50 Hz for a consumption of 55 VA or a current consumption equal to 0.1 A and cos ϕ reduction coefficient k to this number of cycles as indicated by curve 2. For cos ϕ = 0.3: k = 0.6 The electrical durability therefore becomes:1.5 106 operating cycles x 0.6 = 900 000 operating cycles. D. C. Load Limit Curve

Function A : Power on Delay Relay
Description
The timing period T begins on energisation. After timing, the output(s) R close(s). The second output can be either timed or instantaneous. Function: 1 Output Function: 2 Outputs 2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)
Function C : Off-Delay Relay with Control Signal After power-up and closing of the control contact C, the output R closes. When control contact C re-opens, timing T starts. At the end of the timing period, the output(s) R revert(s) to its/their initial state. The second output can be either timed or instantaneous. Function: 1 Output Function: 2 Outputs 2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)
Function D : Symmetrical Flasher Relay (Starting Pulse Off) Repetitive cycle with two timing periods T of equal duration, with output(s) R changing state at the end of each timing period T. The second output can be either timed or instantaneous. Function: 1 Output Function: 2 Outputs 2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)
Function Di : Symmetrical Flasher Relay (Starting Pulse On) Repetitive cycle with two timing periods T of equal duration, with output(s) R changing state at the end of each timing period T. The second output can be either timed or instantaneous. Function: 1 Output Function: 2 Outputs 2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)
Function H : Interval Relay On energisation of the relay, timing period T starts and the output(s) R close(s). At the end of the timing period T, the output(s) R revert(s) to its/ their initial state. The second output can be either timed or instantaneous. Function: 1 Output Function: 2 Outputs 2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)
Function W : Interval Relay with Control Signal Off After power-up and opening of the control contact, the output(s) close(s) for a timing period T. At the end of this timing period the output(s) revert(s) to its/their initial state. The second output can be either timed or instantaneous. Function: 1 Output Function: 2 Outputs 2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.).
