Product description
3.4.7
Connection of a UE410-8DI
A UE410-8DI acts on the cut-off path A/B on a UE410-GU as follows:
•
Input A (I1-I4)
,
QA acts on the global cut-off path.
•
Input B (I5-I8)
,
QB acts on the local cut-off path.
An OR function or a bypass function that acts on the global cut-off path of the UE410-GU
(switch position 7 or 8, input A on the UE410-8DI) is not permitted and will result in a
configuration error (ERROR).
3.4.8
Power-up delay and response time of the UE410-GU
Power-up delay
The power-up delay of the UE410-GU is calculated as follows:
Power-up delay = local power-up delay + (N–1) × global power-up delay
Where:
Local power-up delay = power-up delay for the module on which the emergency stop was
triggered and reset
Global power-up delay = power-up delay of the other modules in the system
N
= number of the UE410-GU modules in the system
You will find the values for the power-up delay on the data sheet in section 11.1.2 “UE410-
GU module” on page 101.
Response times
Extended response time of the overall system on the usage of several UE410-GU
modules!
In a system consisting of several UE410-GU modules connected together, the power-up
delay and the response time are increased depending on the number of UE410-GU mo-
dules connected together. Take this aspect into account on planning your system. Other-
wise the operator of the system will be in danger.
The response time of the UE410-GU is calculated as follows:
Response time = local response time + (N–1) × global response time
Where:
Local response time = response time of the module on which the emergency stop was
triggered
Global response time = response time of the other modules in the system
N
= number of the UE410-GU modules in the system
You will find the values for the response times on the data sheet in section 11.1.2
“UE410-GU module” on page 101.
3.4.9
Diagnostics and troubleshooting for the UE410-GU
If a system with a global emergency stop function comprising several UE410-GU modules
is either entirely or partially at the standstill, then you can determine which module has
triggered the emergency stop as follows:
=
Based on the LED indicators on any UE410-GU module in the system check whether the
emergency stop has been triggered by this module or the direction of the module that
has triggered the global or local emergency stop, see Tab. 15.
