The information presented in Tab. 31 “Response time of the C4000 Select for applications
with and without beam coding” also applies for C4000 Select sender/receiver pairs that
are in the guest 2 position. Identify the response time value that corresponds to your
guest 2 C4000 Select based on the beam code DIP switch setting (i.e. Uncoded, Beam
code 1 or Beam code 2 operation) and the protective height that is used.
Line Description Value
9 Enter the value for the guest 2 response time based on Tab. 31 for
the C4000 Select
10 If floating blanking is enabled, multiply the value on line 9 by 0.50
and enter the result as the line 10 value
11 Add lines 9 and 10 together. Enter the result in line 11 value
12 Multiply line 1 from the host response time calculation by 0.50 and
then add 2 ms. Enter the result as the line 12 value
13 Multiply line 4 from the guest 1 response time calculation by 0.50
and then add 2 ms. Enter the result as the line 13 value
14 Add lines 11, 12 and 13 together. Enter the result in line 14 value.
Line 14 value is the response time of the guest 2 device.
