5.4.7 Programmable Logic Settings
The programmable logic settings consist of settings for six logic
gates, six timer gates, two latches, thirteen blocking gates, and
six output gates. The six output gates (Output Trip1, Output Trip2,
Rly3, Rly4, Rly5, and Output Alarm) are configured by the
"Output Config" settings described previously, therefore they
won't be discussed in this section.
See Section 9, Programmable Logic Application, for detailed
information about the logic functions. This section will only
describe how to set the programmable logic settings. Figure 24
Logic Setting Flowchart, on the following page, shows an
example of how to program Logic Gate 1.
The Figure 24 flowchart is an example of programming Logic
Gate 1 to be a NAND gate of setting group 2 with IN1 "Trip G OC. "
1. Select programmable Logic from the "Setting Main" setting
display menu and press "Enter PB. "
2. Select Logic Gate 1 press "Enter PB. "
3. Press "Enter PB" and choose Function to be NAND with up/
down PBs, press "Enter PB. "
4. Select Set Group using up/down PBs, press "Enter PB" ,
choose Set Group to 2 using up/down PB's, press "Enter PB. "
5. Select IN1 using up/down PBs, press "Enter PB. "
6. Select Trip using up/down PBs and press "Enter PB. "
7. Select G OC using up/down PBs and press "Enter PB. "
8. Select G OH to be Direct, then press "Enter PB" , which finishes
Logic Gate 1 programming.
Press "Previous PB" to back out of Logic Gate 1 programming
and return to "Programmable Logic" display to program other
logic gates.
Logic Gates 1 through 6:
All six logic gates contain the same settings as shown below.
Function:
Set to OR, AND, NOR, NAND, Disable. The Function setting
defines the output of the logic gates with inputs IN1, IN2, IN3,
and IN4. The default setting is OR.
Setting Group:
This setting defines the Setting Group for which the logic gate
programming is active. This setting is also linked to the System
Config settings, which is where the total number of settings
groups (1 to 4) is programmed.
IN1, IN2, IN3, IN4:
These settings define the logic inputs to Logic Gates 1 through 6.
See the settings table and Section 9.6 for a complete description
of the logic input settings.
Timer Gates 1through 6:
All six timer gates contain the same settings as shown below.
Setting Group:
This setting defines the Setting Group for which the timer gate
programming is active. This setting is also linked to the System
Config settings, which is where the total number of settings
groups (1 to 4) is programmed.
In:
This setting defines the logic input to Timer Gates 1 through 6.
See the settings table and Section 9 for a complete description of
the logic input settings.
Delay Unit:
This setting selects if the delay is based on cycles or seconds.
On Delay (c) :
Sets the number of cycles or seconds the Timer Gate input must
remain active before the Timer Gate output becomes active. See
Section 9 for a detailed description of the logic settings.
Off Delay (c) :
Sets the number of cycles or seconds the Timer Gate output will
remain active after the Timer Gate input becomes inactive. The
Off Delay has no affect unless the Timer Gate output is active
when the input becomes inactive. See Section 9 for a detailed
description of the logic settings.
Logic Latches 1 and 2:
Both logic latches contain the same settings as shown below.
Setting Group:
This setting defines the Setting Group for which the logic latch
programming is active. This setting is also linked to the System
Config settings, which is where the total number of settings
groups (1 to 4) is programmed.
Set In:
This setting defines the Set Input to the Logic Latch. The latch
output goes active when the Set Input is active. The output
remains latched in the active state until the Reset is activated.
See the settings table and Section 9 for a complete description of
the logic input settings.
Reset In:
This setting defines the Reset Input to the Logic Latch. The latch
output is reset when the Reset Input is active. If both the Set Input
and Reset Input are active, the latch output is inactive. See the
settings table and Section 9 for a complete description of the
logic input settings.
Blocking Logic Gates for IOC and TOC:
All 12 blocking logic gates contain the same settings as shown
below. When the output of the blocking logic gate is active,
operation of the associated IOC or TOC protection function is
blocked. The IOC or TOC function will still pickup, but not trip.
Function:
Set to OR, AND, NOR, NAND, Disable. The Function setting
defines the output of the blocking logic gates with inputs IN1,
IN2, IN3, and IN4. The default setting is Disable. See Section 9 for
a detailed description of the logic settings.
Setting Group:
This setting defines the Setting Group for which the logic gate
programming is active. This setting is also linked to the System
Config settings, which is where the total number of settings
groups (1 to 4) is programmed.
IN1, IN2, IN3, IN4:
These settings define the logic inputs to Logic Gates 1 through 6.
See the settings table and Section 9 for a complete description of
the logic input settings.
