Note 2 The intrinsic safe apparatus and wirings shall be accordance to following formulas; for example: Ui ≥ Uo Ii ≥ Io Pi ≥ Po Ci+Cc ≤ Co Li+Lc ≤ Lo *: Therefore, the values are allowable only at Li ≤ 1%Lo and Ci ≤ 1%Co of the intrinsic safe apparatus. (In the case of 50% of Co and Lo parameters are applicable,the maximum capacitance allowed shall not be more than Co = 1 µF for IIB and Co= 600 nF for IIC.)

1. A maximum of ve monitor contacts from safety input devices can be connected to the auxiliary input terminals. In addition, non-safety input devices can also be connected to the auxiliary input terminals.

2. On auto reset (auto start) models, when the safety condition is met (two safety inputs are both on), safety outputs are turned on automatically. Connect the reset (start) input terminals Y1 and Y2 together except for the following cases: When connecting a contactor or force guided relay to the safety output of the EB3N, connect the NC contacts of the contactor or force guided relay to the reset (start) input terminals Y1 and Y2 of the EB3N for use as a backcheck input signal.

3. On manual reset (manual start) models, while the safety condition is met (two safety inputs are both on), safety outputs are turned on at the falling edge of the reset switch (start switch) signal (OFF

ON OFF) (start off check).

Manual reset (manual start) models have a monitoring function of reset switch contacts (detection of welded contacts). Use NO contacts of a momentary switch for the reset (start) input. When connecting a contactor or force guided relay to the safety output of the EB3N, connect the NC contacts of the contactor or force guided relay to the reset (start) input terminals Y1 and Y2 of the EB3N for use as a backcheck input signal.

Selection Guide

1. Selecting the reset (start) function Auto reset (auto start): Select this model when connecting safety control devices, such as safety relay modules or safety controllers, to the EB3N safety

outputs to set up a safety system, using the reset (start) function of the safety control device. Select this model when connecting contactors or force guided relays to the EB3N safety outputs to set up a safety system, and a

risk assessment on the entire system has not found any safety problem in using auto reset (auto start).

Manual reset (manual start): Select this model when connecting contactors or force guided relays to the EB3N safety outputs to set up a safety system, and a

risk assessment on the entire system has found that manual reset (manual start) is necessary.

2. Selecting the auxiliary outputs Without auxiliary outputs: Select this model when the operating status of safety input devices are not monitored. With auxiliary outputs: Select this model when the operating status of safety input devices are monitored or when non-safety input devices are also con-

nected.
