Electrical Installation

It is not possible to give exact wiring instructions for a Safety Module which interfaces to a multitude of machine control configurations.
The following guidelines are general in nature.
The Safety Module has no delay function. Its output relay contacts open within 35 milliseconds after a safety input opens. This classifies
the Safety Module as functional stop “Category 0”, as defined by NFPA 79 and IEC/EN 60204-1.

WARNING: Safety Categories
The level of safety circuit integrity can be greatly impacted by the design and installation of the safety
devices and the means of interfacing of those devices. A risk assessment must be performed to deter-
mine the appropriate safety circuit integrity level or safety category as described by ISO 13849-1
(EN 954-1) to ensure that the expected risk reduction is achieved and that all relevant regulations
and standards are complied with.

CAUTION: Shock Hazard
Always disconnect power from the Banner device and the guarded machine before making any connec-
tions or replacing any component. Use extreme caution to avoid electrical shock at all times.

Connection of Power to the Safety Module

The Safety Module requires a 24V ac/dc supply voltage (see Specifications). Use extreme caution whenever installing ac power. Use a
minimum of 16 to 18 AWG wire for power and output connections. Use a minimum of 20 AWG wire for all other terminal connections. A
hand-operated supply disconnect and over-current protection (e.g., a circuit breaker) must be provided per ANSI NFPA79 and IEC/
EN60204-1.

Connection of Input Switches (Hand Control Actuators)

Connect the actuation devices to the Module as shown in the following wiring diagrams. SW1 and SW2 must both have normally open
and normally closed output contacts, or two current-sourcing complementary outputs each, all capable of reliably switching 25 mA at 24V
dc (nominal). If hand controls have metal housings, the housings must be connected to protective earth ground.
If STB Touch Buttons with PNP outputs are used, the entire STB/AT-FM-10K system must be supplied with 24V dc. Electronic
actuation devices, including STB Touch Buttons, must share the same voltage supply with the Safety Module.

WARNING: Use of Electronic Hand Controls
Electronic (powered) hand controls include optical touch buttons, capacitive touch buttons and similar de-
vices. When electronic hand controls are used as input switches for a Safety Module, the hand con-
trols and the Safety Module must be powered from the same voltage source. Failure to do so cre-
ates a potentially dangerous condition, which could result in serious injury or death.
If power is applied to the Safety Module before power is applied to the electronic hand controls, an output
from the Safety Module could result and may trigger machine motion. Also, electronic hand controls can-
not guarantee the state of their outputs at the time power is applied to them.
