Description
EmergencyStopRelayTypeBO5988compliesfullywiththe
requirements of the standard specifications referred to on page 3 of
this publication. It is a derivative of models BN 5983 / BD 5987 utilising
fail-safe control logic to offer greatly extended control capability within a
compact 100 mm wide DIN rail mounted enclosure.
Circuit Connections
The adjacent circuit (diag. 1) is for standard 2 channel input, manual
reset operation.
The OFF and the EMERGENCY STOP buttons are connected in
series between terminals S11/A3(+) and S12/S22.
The ON/button Button is connected between terminals Y1 and Y2.
The a.c. auxiliary supply is connected to terminals A1 and A2. If a
24V d.c. auxiliary supply is used it should be connected to terminals
S11/A3(+) and A4(–).
The circuits to be tripped are connected to terminals 13–14, through
to 63–64. Terminals 81–82 are dedicated to remote signalling and
must not be used for direct control purposes. The bridges across
S21/S23 and X1/X2 are left in place unless another mode of
operation is required. (see diags 2, 3 and 4).
For additional security an insulation monitoring relay may be
connected to monitor terminal PE(–) to ground. (Details on request).
When used with cross fault monitoring of the EStop button circuit
diagram 3, this relay is suitable for Category 4 applications.
Indication
The relay is equipped with three green LEDs. When illuminated they indicate the
healthy condition of the auxiliary supply and circuits
K2–K3.
