Figure 13-7. Mode 3 (One-Shot Retriggerable) Timing Example
Mode 4 - Oscillator
Because this operating mode is not intended for general use, no testing procedure is available.
Information about Mode 4 is available in Section 4, Protection and Control, General Purpose Logic
Timers.
Mode 5 - Integrating
Step 1: Prepare the 62 Timer for Mode 5 testing by transmitting the commands in
Table 13-96.
Table 13-96. x62 Mode 5 Test Commands
Command Purpose
A= Gains write access.
SL-N=NONE Zero out custom logic settings. Overwrite with LOGIC=NONE settings.
Y Confirm overwrite.
SL-N=T62 Sets T62 as custom logic name.
SL-43=2 Enables 43 Switch ON/OFF mode.
SN-43=62_INI,PU,DO Name Switch 43 to make SER easier to read.
SL-62=5,43,0 Enables 62 integrating mode, 43 initiate, no blocking.
S0-62=15s,5s Sets T1 at 15 seconds. Sets T2 at 5 seconds.
EXIT;Y Exit and save settings.
Step 2: Transmit the commands of
Table 13-97 to the relay. These commands supply a block input to
the 62 Timer by changing the 43 Switch state to TRUE.
Table 13-97. x62 Mode 5 Timer Initiate Commands
Command Purpose
A= Gains write access.
CS-43=1 Selects 43 for TRUE operation.
CO-43=1 Executes 43 TRUE operation.
Wait no longer than 10 seconds to interrupt the T1 timer.
NOTE
The CS and CO commands of Table 13-97 are performed three times. Follow the
timing sequence to illustrate timer mode action. The time delay settings may be
increased if difficulty is encountered with repeating the 43 Switch actions.
