PICO-GUARD Controller
Instruction Manual
4.1 Periodic Checkout Requirements
To ensure continued reliable operation, the System must be
checked out periodically.
At every shift change, power-up and machine setup change,
the Daily checkout should be performed; this checkout may be
performed by a Designated or Qualified Person (see
Section 6.4).
Semi-annually,
the system and its interface to the guarded
machine should be thoroughly checked out; this checkout
must be performed by a Qualified Person (see Section 6.5).
A copy of these test results should be posted on or near the
machine.
Whenever changes are made to the System
(either a new
configuration of the PICO-GUARD System or changes to the
machine), the Commissioning Checkout should be performed
(see Section 6.3)
4.2 System Configuration Settings
System configuration settings are made to two identical
banks of DIP switches on the controller’s configuration panel.
The configuration panel is located behind the access cover.
The access cover is opened using the security hex wrench
provided (see Figure 4-1).
Change configuration settings
only
when the system is OFF.
NOTE:
The corresponding pairs of DIP switches must be set
identically
(e.g., both banks set for Auto Power-Up) for
the System to operate. If they have different settings,
a fault condition will occur. See Section 5 for fault
identification and troubleshooting procedures.
After configuration settings are set and verified, close the
access cover and secure it using the security hex wrench.
Auto/Manual Power-Up
is selected on two DIP switches as
shown in Figure 4-2. If the switches are set for Auto Power-
Up, the controller will automatically perform a system reset
on power-up, after the internal system tests are completed. If
the switches are set for Manual Power-Up, the controller will
require a system reset at power-up. The controller indicates it
is ready for a system reset after power-up by double-flashing
the System Reset indicator (see Figure 4-3).
Trip or Latch Output
is selected on two DIP switches as shown
in Figure 4-2. If the switches are set for Trip Output (T), the
controller will turn the OSSD outputs ON automatically when
all active (ON) optical channels are closed (light received). If
the switches are set for Latch Output (L), the controller will
require a system reset when all active (ON) optical channels
are closed (light received). The controller indicates it is ready
for a system reset to clear the latch condition by single-
flashing the System Reset indicator (see Figure 4-3).
EDM options
are selected via two DIP switches as shown
in Figure 4-2. For 1-Channel Monitoring, set both EDM DIP
switches to 1. For 2-Channel Monitoring or No Monitoring,
set both EDM DIP switches to 2. See Section 3.9.3 for more
information.
Optical Channels
are enabled via four pairs of DIP switches as
shown in Figure 4-2. Each optical channel is enabled by setting
its pair of switches to ON, or disabled by setting them to OFF.
At least one optical channel must be ON at all times or a fault
condition will occur.
