Description
In the Schedule number listed, the Start Meter signal has been set up to turn on or off too long after the node the SS[] or SE is attached to. Currently, if this signal is set up to turn on or off greater than 100ms after the node, this warning will be posted and the signal will fire 100ms after the node. These are the formulas used to determine when this signal will be turned on or off relative to the node for seal schedule 'n': For SS[n]: Time_Before = PRE_PRESSURE_DELAY + EQUIPMENT_DELAY - GUNON_DELAY For SE[n]: Time_Before = DE_PRESSURE_DELAY + EQUIPMENT_DELAY - GUNOFF_DELAY Note that a NEGATIVE Time_Before means
Remedy
There is no real danger in this condition. You should be aware that if you try to turn this signal on or off after 100ms AFTER the node, the signal will always be fired 100ms after the node and this warning will be posted. To correct this problem, make the pre/de_pressure_delay or equipment_delay more positive or the gunon/gunoff delay more negative, to move the firing of the signal up earlier.
