The start of injection signal (SOI) of the side mounted injector is the same as for the central injector in case of using one injector.
The purpose of this study was twofold: on one hand to assess the latest version of RELAP5/MOD3.3 Patch 05 and on the other hand to better understand the plant response to the event with the reactor trip and safety injection signal actuation.
Some of the targeted objects, whether conductive or nonconductive, were placed in a few different locations inside the testing vessel and exposed to various injection signal frequencies: 300, 400, 500, 900, and 1000 kHz.
In summary, mold filling is triggered by the injection signal. The sprue is filled after around 0.017 s.
It requires that the frequency band of the injection port is sufficient and the injection signal coupled into the equipment B is distortion-free.
The injection signal is typically generated using a modified PWM method or by application of specific power-on states, upon which current response is measured.
In divide-by-three ILFDs with direct forcing of the injection signal, the current signal is injected directly in the oscillator across the LC-tank and the locking takes place according to a mechanism different from the mixing between signals [10], usually invoked to explain the process of frequency division [11-13].
Methods to obtain these parameters are several species and one of them is the injection signal method (Sungmin, 2010).
This model describes the well-known topology of ILFDs based on two cross-coupled MOS devices with a tail device, through which the injection signal is applied [9,12].
The LC tank and the transconductor represent the basic oscillator that is perturbed by the injection current (in(v, vin), which depends on both the injection signal vin, and the tank voltage v.

The control steps users through a series of phases allowing control over water temperature, wash speed, mechanical action and chemical injection; boasts expanded mechanical action programmability to include duration and RPMs; has 12 standard chemical injection signals; and features a vastly improved chemical delivery system, in which chemicals are diluted with water before being introduced to linen inside the washer drum.
